عَنْ ثَوْبَانَ مولى رسول الله صلى الله عليه وسلم، قَالَ: “كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم إِذَا انْصَرَفَ مِنْ صَلاَتِهِ اسْتَغْفَرَ ثَلاَثًا وَقَالَ ‏ “‏ اللَّهُمَّ أَنْتَ السَّلاَمُ وَمِنْكَ السَّلاَمُ تَبَارَكْتَ ذَا الْجَلاَلِ وَالإِكْرَامِ ‏"‏ ‏.‏ قَالَ الْوَلِيدُ فَقُلْتُ لِلأَوْزَاعِيِّ كَيْفَ الاِسْتِغْفَارُ قَالَ تَقُولُ أَسْتَغْفِرُ اللَّهَ أَسْتَغْفِرُ اللَّهَ ‏.‏ “ صحيح مسلم

Thauban reported: When the Messenger of Allah (ﷺ) finished his prayer. He begged forgiveness three times and said: O Allah! Thou art Peace, and peace comes from Thee; Blessed art Thou, O Possessor of Glory and Honour. Walid reported: I said to Auza'i: How is the seeking of forgiveness? He replied: You should say: I beg forgiveness from Allah, I beg forgiveness from Allah." Sahih Muslim 591

عن عائشة أم المؤمنين رضي الله عنها قالت: مَا رَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم ضَاحِكًا حَتَّى أَرَى مِنْهُ لَهَوَاتِهِ، إِنَّمَا كَانَ يَتَبَسَّمُ‏.‏ قَالَتْ وَكَانَ إِذَا رَأَى غَيْمًا أَوْ رِيحًا عُرِفَ فِي وَجْهِهِ‏.‏ قَالَتْ يَا رَسُولَ اللَّهِ إِنَّ النَّاسَ إِذَا رَأَوُا الْغَيْمَ فَرِحُوا، رَجَاءَ أَنْ يَكُونَ فِيهِ الْمَطَرُ، وَأَرَاكَ إِذَا رَأَيْتَهُ عُرِفَ فِي وَجْهِكَ الْكَرَاهِيَةُ‏.‏ فَقَالَ ‏"‏ يَا عَائِشَةُ مَا يُؤْمِنِّي أَنْ يَكُونَ فِيهِ عَذَابٌ عُذِّبَ قَوْمٌ بِالرِّيحِ، وَقَدْ رَأَى قَوْمٌ الْعَذَابَ فَقَالُوا ‏{‏هَذَا عَارِضٌ مُمْطِرُنَا‏}‏‏"‏ صحيح البخاري

Narrated `Aisha: (the wife of the Prophet), I never saw Allah’s Messenger (ﷺ) laughing loudly enough to enable me to see his uvula, but he used to smile only. And whenever he saw clouds or winds, signs of deep concern would appear on his face. I said, “O Allah’s Messenger (ﷺ)! When people see clouds they usually feel happy, hoping that it would rain, while I see that when you see clouds, one could notice signs of dissatisfaction on your face.” He said, “O `Aisha! What is the guarantee for me that there will be no punishment in it, since some people were punished with a wind? Verily, some people saw (received) the punishment, but (while seeing the cloud) they said, ‘This cloud will give us rain.' “  Sahih AlBukhari

“And place light in my heart.”

A line from a du’a (supplication to God) which the Prophet Muhammad (peace be upon him) would say, sometimes on his way to the Mosque and other times in prayer. The full supplication is as follows: 

( وَعَنْ ابْنِ عَبَّاسٍ { أَنَّ النَّبِيَّ صلى الله عليه وسلم صَلَّى فَجَعَلَ يَقُولُ فِي صَلَاتِهِ أَوْ فِي سُجُودِهِ :

اللَّهُمَّ اجْعَلْ فِي قَلْبِي نُورًا , وَفِي سَمْعِي نُورًا , وَفِي بَصَرِي نُورًا , وَعَنْ يَمِينِي نُورًا , وَعَنْ شِمَالِي نُورًا , وَأَمَامِي نُورًا , وَخَلْفِي نُورًا , وَفَوْقِي نُورًا , وَتَحْتِي نُورًا , وَاجْعَلْ لِي نُورًا أَوْ قَالَ : وَاجْعَلْنِي نُورًا } . مُخْتَصَرٌ مِنْ مُسْلِمٍ )

Ibn ‘Abbas said that one of the du’as that the Prophet made during in his prostration was:

“O Allah, place light in my heart, light in my tongue, light in my hearing, light in my sight, light behind me, light in front of me, light on my right, light on my left, light above me and light below me; place light in my sinew, in my flesh, in my blood, in my hair and in my skin; place light in my soul and make light abundant for me; make me light and grant me light.” (Transmitted by Muslim and others.)
