Ensure that all of his obligations are complete, including the five daily prayers, both inwardly and outwardly, for prayer is the pillar of Deen
—  Imam Ibn Taymiyyah | ‘Mukhtasar Al-Fataawal Misriyya’

The noun ‘modesty’ (haya) is derived from ‘life’ (al-hayah), so the heart that is alive- its owner is also alive- and it contains modesty which prevents it from performing evil & despicable actions, because in the modesty of the heart lies its immunity from these types of actions. This is why the Prophet (ﷺ) said

“Modesty is from faith.”

-Amrad Al-Qalub Wa Shafa'uha by Imam Ibn Taymiyyah.

Revive a Sunnah - Two Rak'ah for Repentance

Abu Bakr As-Siddiq (Radhi Allahu Anhu) said the Prophet (Salla’Allaahu Alayhi wa Salam) said, “Any person who sins then performs wudu correctly and prays and afterward seeks Allah’s forgiveness Allah forgives him.” Then As-Siddiq (Radhi Allahu Anhu) recited the verse” And those who when they commit an indecency or do injustice to their souls remember Allah and ask forgiveness for their faults - and who forgives the faults but Allah, and (who) do not knowingly persist in what they have done. {Al-Imran: 135}

Collected by Abu Dawud (1521) At-Tirmithi (406) Ibn Majah (1395) and Ahmed (½-8-9-10) graded as being Hasan by At-Tirmithi, Ibn ‘Adee, Ibn Kathir, At-Thahabee and Al-Albani (may Allah have mercy on them all)

Imam Ibn Taymiyyah (rahmatullah alaih) said, It is a recommended act for every person who sinned to perform Wudu then pray two Rak’ah.
[Majmu’ Fatawaa vol 21 / 139]

The Qur’an removes all the sicknesses that invoke false desires until the heart becomes pure and therefore its desires become pure and it returns to the natural state (fitrah) that it was created in, just as the body returns to the natural state upon being treated.

The heart will be nurtured with faith and the Qur’an such that it will become strong, for indeed the purification of the heart is like the growing of the body.

-Amrad Al-Qalub Wa Shafa’uha by Imam Ibn Taymiyyah.

The main reason why anyone is misguided is because he gives precedence to his own opinion over the guidance revealed from Allah, and he prefers to follow his own whims rather than the commands of Allah.
—  Imam Ibn Taymiyyah | Al-’Ubudiyyah

Imam Ibn Taymiyyah رحمه الله:
“The truth is like pure gold, whenever tested (it has) increased in quality.”
