What is your advice for someone who wants to seek knowledge?
السلام عليكم ورحمة الله وبركاته
 Sincere intention
Why are you seeking knowledge? To please Allāh or to gain employment or for status? As seekers of knowledge, it’s important to always renew your intentions, It was narrated from ‘Umar ibn Al-Khaṭṭāb – Allāh be pleased with him – said:
“I heard Allāh’s Messenger (ﷺ) saying, ‘The reward of deeds depends upon the intentions and every person will get the reward according to what he has intended. So whoever emigrated for worldly benefits or for a woman to marry, his emigration was for what he emigrated for.’” — Sahīh al-Bukhārī (1)
It was also narrated from the Prophet (ﷺ), that he said:
“Perished be the slave of the Dīnār and Dirham, of Qatīfah (thick soft cloth) and Khamīsah (i.e. money and luxurious clothes); as he is pleased if these things are given to him, and if not, he is displeased. Let such a person perish and relapse, and if he is pierced with a thorn, let him not find anyone to take it out for him…” — Al-Bukhārī (6/61)
And Allāh - may He be exalted - said:
‘Whosoever desires the life of the world and its glitter - to them We shall pay in full (the wages of) their deeds therein, and they will have no diminution therein. They are those for whom there is nothing in the Hereafter but Fire; and vain are the deeds they did therein. And of no effect is that which they used to do.’ — Sūrat Hūd: (11:15-16)
 Study with Ihsān (excellence)
Grand intentions require grand efforts. We must strive to study to the best of our ability and aim for excellence, not perfection.
It was narrated from Abū Ya’la Shaddād bin Aws – Allāh be pleased with him – that the Prophet (ﷺ) said:
‘Verily Allāh has prescribed ihsān (proficiency, perfection) in all things. So if you kill then kill well; and if you slaughter, then slaughter well. Let each one of you sharpen his blade and let him spare suffering to the animal he slaughters.’ – 40 Hadith Nawawi (17)
Allāh, the Most High, says,
“…let those who strive, strive for this.” - Sūrat al-Muṭaffifīn (83:26)
Al-Hāfidh Ibn Rajab ‘l-Hanbalī said:
“…Know that the soul loves to attain rank and position above its like and this is what produces pride and envy. However the intelligent one strives, for everlasting and perpetual rank which is in Allāh’s pleasure, and in nearness to Him, and he turn away from fleeting and short-lived rank which is followed by Allāh’s Wrath and Anger and means the person’s downfall, lowness and his distance from Allāh and being banished away from Him. So this is the second kind of eminence which is blameworthy and it is wrongful haughtiness and eminence upon the earth.” – The Evil of Craving for Wealth and Status (pg. 34)
 Exhbit Reliance (al-Tawakkul)
While doing our best, we must rely upon Allāh for the results. We must trust that He will make things easy for us and will grant us success.
It was narrated from Abū Hurayrah – Allāh be pleased with him – that the Prophet (ﷺ) said:
“Indeed Allāh Most High says: ‘I am as My slave thinks of Me, and I am with him when He calls upon Me.’” – Jami` at-Tirmidhi (2388)
It is the highest station of Tawhīd. Indeed no matter is achieved except by having reliance in Allāh and seeking His aid and assistance (al-Istiʾānah).
It was narrated from Saʾīd b. Jubayr - Allāh have mercy upon him - said:
“Reliance in Allāh is the vessel of faith.” – Musannaf Ibn Abī Shaybah (7/202)
Ibn al-Qayyim – Allāh have mercy upon him – said:
“If a slave depended upon Allāh with due reliance in moving a mountain from its place, and he was commended to do that, he would surely move it!” – Madārij al-Sālikīn (1/81)
 Pick your companions wisely
Strive to choose righteous friends who are preoccupied with seeking knowledge and are of a good nature, who can help you in achieving your aim, add to the benefits you have already gained, encourage you to seek more knowledge and stop you from feeling bored and tired; friends who are religiously-committed, trustworthy and of good character, who are sincere towards Allāh and who are not merely messing about.
It was narrated from Abū Hurayrah – Allāh be pleased with him – that the Prophet (ﷺ) said:
“A person follows (imitates) the religion of his friends, therefore let each one of you look at the one he befriends.” [Abū Dāwūd, Tirmidhī, Aḥmad, As-Sahīhah (927)]
Also, It was narrated from Abū Mūsā Al-Ash’arī narrated that the Prophet (ﷺ) said:
“The example of an evil companion is like an ironsmith. Either he burns your clothes or you smell a foul odor from him.” [Bukhārī & Muslim]
‘Abdu’llāh Yūsuf ‘Azzām said:
“A group of friends are all like each other, and the longer the friendship lasts, the closer the character and manners of each person in the group will be to the others. Do not believe that a good person can live for long with a corrupt person, unless the corrupt person improves and follows the example of the good person.
This is why you should look for the good people, and a friend is like a chain: he will either drag you into Paradise, or drag you into Hell. He will either cause you problems or he will help you solve your problems.” – At-Tarbiyyah Al-Jihādiyyah Wal-Bina (5/35)
Ibn ‘Uthaymīn said:
“Stay away from people with evil and wicked character.” – Mushkilāt Ash-Shabāb (p. 31-32)
 Beware of self-admiration
Beware of self-admiration and being deceived (by self-pride and conceit), for verily, it is how righteous people are destroyed.
Imām Ash-Shāfiʿī said:
“If you fear that self-admiration will affect your deeds, remember the One Whom you are trying to please, what blessings you are trying to seek and what kind of punishment you are seeking to escape. The one who thinks of that will see his deeds as insignificant.” – Siyar A’lām An-Nubulā (10/42)
“The way to rid oneself of self-admiration is to know that knowledge is a blessing from Allaah (swt) and a complete favour. That belongs to Allaah (swt) which He takes away, and that belongs to Him which He gives, and everything has an appointed time with Him, so a person should not develop self-admiration for something that he had nothing to do with and has no control over, and it is not certain that it will last.” – Al-Majmū’ (1/55)
 Eat seldom as possible
Extravagance leads overstepping the mark, which means eating beyond the point of fullness. This is not limited to one or two or three meals a day. A person may eat one meal a day and eat extravagantly during that meal. Or he may eat three meals without being extravagant.
an-Nu’mān bin Bashīr narrated that ‘Umar bin al-Khattāb – Allāh be pleased with them both – was mentioning the poverty that the people had become stricken with, saying:
“I saw the Messenger of Allāh (ﷺ) spend the whole day upset because of hunger, as he could not get even low quality dates with which to fill his stomach.” – Sahīh Muslim (2978)
It was reported that Abū Hurayrah – Allāh be pleased with him – passed by a group of people who were eating a roasted sheep, and they invited him to sit and eat with them. He refused, saying:
“The Messenger of Allāh (ﷺ) left this world without even satisfying his hunger with barley bread.” – Sahīh al-Bukhārī’ (5414)
It was narrated that And Anas bin Mālik – Allāh be pleased with him – said:
“The Prophet (ﷺ) never ate his meals at a dining table or in an individual plate, and he never ate thin, well-baked bread until he died.” – Sahīh al-Bukhārī’ (5415)
It was reported that Shaykh al-Islām Ibn Taymiyyah:
“Was never heard asking for food - dinner or supper – no matter how long he remained busy with some matter related to knowledge and action. Rather, he would sometimes be given food that he would leave for a long time before even turning to it, and if he ate from it, would only eat small bits. He would never mention the delights of this world, and would never speak or ask about it. Rather, all of his concern and conversation was in seeking the Hereafter and what could bring him closer to Allāh, the Exalted.” – Ghāyat al-Amānī (2/173)
 Sleep seldom as possible
Sleeping more than the body needs will make one lazy in worship and will make one slow in thinking.
Allāh praised the righteous people, referring to them as good-doers because they would sleep very little at night:
“Verily, the righteous will be in the midst of gardens and springs, taking joy in the things which their Lord has given them. Indeed, they were good-doers. They used to sleep little at night, and in the hours before dawn, they were found asking for Forgiveness, and in their wealth was a right for the beggar and the poor.” – Surat adh-Dhāriyāt (51:15-19)
As for sleeping:
“The student of knowledge should reduce it as much as he can without hurting his body and mind, and he should not sleep more then eight hours a night – one third of his time – and if he is able to sleep less than this, he should.” – Tadhkirat as-Sāmi’ wal-Mutakallim (p. 77)
az-Zarnūjī – may Allāh have Mercy on him – said:
“al-Hasan bin Ziyād began studying at the age of 80, and for forty years, he did not sleep an entire night on his bed, and Muhammad bin al-Hasan ash-Shaybānī would not sleep at night. He would place his books in front of him, and if he became bored of one book, he’d move on to another. He would also place in front of him a container of water that he’d use to keep himself awake, saying: “Sleep comes from heat, and one must repel it with cold water.”” – Ta’līm al-Muta’allim wa Turuq at-Ta’allum’ (p. 23)
Ibn Jarīr at-Tabarī said:
“Their rest and sleep took up a very small portion of the night.” – Tafsīr al-Qur’ān al-‘Adhīm (4/233)
al-Hasan al-Basrī said:
“They would spend the night in prayer, and would not sleep except for a short time. Then, when they had some energy, they would make istighfār until dawn.” – Tafsīr al-Qur’ān al-‘Adhīm (4/233)
Qatādah said that al-Ahnaf bin Qays would say:
“They would sleep for only a little while,” and then say: “I am not from those described in this verse.” – Tafsīr al-Qur’ān al-‘Adhīm (4/233)
Ibn ‘Abbās – Allāh be pleased with him – and Ibrāhīm an-Nakha’ī said:
“They would sleep very little.” – Tafsīr al-Qur’ān al-‘Adhīm (4/233)
 Revision is a MUST
If a person memorises different texts covering a variety of subjects, then every month, one should revise all those texts which they have memorised, and this will make one’s memorisation firm, and facilitate quick recollection.
Ibn al-Jawzī said:
“al-Ḥasan (meaning ibn Abī Bakr an-Naysābūri) told us a story about a jurist who would repeat his lesson many times in his house.
So an elderly woman who was in his house said to him, ‘By Allāh, even I have memorised it! (because the man was repeating so many times).’ So the man asked her recite it to him, and so she did.
After a few days the man came back to the woman and said, ‘Recite to me that lesson’ to which she replied, ‘I did not memorise it (meaning she had forgotten).’
The man said, ‘I repeated the lesson so that I am not afflicted with that which afflicted you (i.e. forgetfulness).‘”
– Mutun Tālib al-‘Ilm by Shaykh ‘Abdul Muhsin al-Qāsim
Moral of the story: Revision is a must for anything you learn, especially that which you memorise!
