One night I slept at the house of Maimuna. The Prophet ﷺ woke up, answered the call of nature, washed his face and hands, and then slept. He got up (late at night), went to a water skin, opened the mouth thereof and performed ablution not using much water, yet he washed all the parts properly and then offered the prayer. I got up and straightened my back in order that the Prophet ﷺ might not feel that I was watching him, and then I performed the ablution, and when he got up to offer the prayer, I stood on his left. He caught hold of my ear and brought me over to his right side. He offered thirteen rakʿat in all and then lay down and slept till he started blowing out his breath as he used to do when he slept. In the meantime Bilal informed the Prophet ﷺ of the approaching time for the (Fajr) prayer, and the Prophet offered the Fajr (Morning) prayer without performing new ablution. He used to say in his invocation, Allahumma ijʿal fi qalbi nuran wa fi basari nuran, wa fi samʿi nuran, waʿan yamini nuran, waʿan yasari nuran, wa fawqi nuran, wa tahti nuran, wa amami nuran, wa khalfi nuran, wajʿal li nuran." Kuraib (a sub narrator) said, "I have forgotten seven other words, (which the Prophet ﷺ mentioned in this invocation). I met a man from the offspring of Al-ʿAbbas and he narrated those seven things to me, mentioning, '(Let there be light in) my nerves, my flesh, my blood, my hair and my body,' and he also mentioned two other things."  

بِتُّ عِنْدَ مَيْمُونَةَ فَقَامَ النَّبِيُّ ﷺ فَأَتَى حَاجَتَهُ غَسَلَ وَجْهَهُ وَيَدَيْهِ ثُمَّ نَامَ ثُمَّ قَامَ فَأَتَى الْقِرْبَةَ فَأَطْلَقَ شِنَاقَهَا ثُمَّ تَوَضَّأَ وُضُوءًا بَيْنَ وُضُوءَيْنِ لَمْ يُكْثِرْ وَقَدْ أَبْلَغَ فَصَلَّى فَقُمْتُ فَتَمَطَّيْتُ كَرَاهِيَةَ أَنْ يَرَى أَنِّي كُنْتُ أَتَّقِيهِ فَتَوَضَّأْتُ فَقَامَ يُصَلِّي فَقُمْتُ عَنْ يَسَارِهِ فَأَخَذَ بِأُذُنِي فَأَدَارَنِي عَنْ يَمِينِهِ فَتَتَامَّتْ صَلاَتُهُ ثَلاَثَ عَشْرَةَ رَكْعَةً ثُمَّ اضْطَجَعَ فَنَامَ حَتَّى نَفَخَ وَكَانَ إِذَا نَامَ نَفَخَ فَآذَنَهُ بِلاَلٌ بِالصَّلاَةِ فَصَلَّى وَلَمْ يَتَوَضَّأْ وَكَانَ يَقُولُ فِي دُعَائِهِ اللَّهُمَّ اجْعَلْ فِي قَلْبِي نُورًا وَفِي بَصَرِي نُورًا وَفِي سَمْعِي نُورًا وَعَنْ يَمِينِي نُورًا وَعَنْ يَسَارِي نُورًا وَفَوْقِي نُورًا وَتَحْتِي نُورًا وَأَمَامِي نُورًا وَخَلْفِي نُورًا وَاجْعَلْ لِي نُورًا قَالَ كُرَيْبٌ وَسَبْعٌ فِي التَّابُوتِ فَلَقِيتُ رَجُلاً مِنْ وَلَدِ الْعَبَّاسِ فَحَدَّثَنِي بِهِنَّ فَذَكَرَ عَصَبِي وَلَحْمِي وَدَمِي وَشَعَرِي وَبَشَرِي وَذَكَرَ خَصْلَتَيْنِ  

When the Prophet ﷺ got up at night to offer the night prayer, he used to say: "Allahumma laka l-hamdu; Anta nuras-samawati wal ardi wa man fihinna. wa laka l-hamdu; Anta qaiyim as-samawati wal ardi wa man flhinna. Wa lakaI-hamdu; Anta-l-,haqqun, wa wa'daka haqqun, wa qauluka haqqun, wa liqauka haqqun, wal-jannatu haqqun, wannaru haqqun, was-sa atu haqqun, wan-nabiyyuna huqqun, Mahammadun haqqun, Allahumma laka aslamtu, wa Alaika tawakkaltu, wa bika amantu, wa ilaika anabtu, wa bika Khasamtu, wa ilaika hakamtu, faghfirli ma qaddamtu wa ma akh-khartu, wa ma asrartu, wa ma a'lantu. Anta al-muqaddimu, wa anta al-mu-'akhkhiru. La ilaha il-la anta (or La ilaha ghairuka)"  

عَنِ ابْنِ عَبَّاسٍ كَانَ النَّبِيُّ ﷺ إِذَا قَامَ مِنَ اللَّيْلِ يَتَهَجَّدُ قَالَ اللَّهُمَّ لَكَ الْحَمْدُ أَنْتَ نُورُ السَّمَوَاتِ وَالأَرْضِ وَمَنْ فِيهِنَّ وَلَكَ الْحَمْدُ أَنْتَ قَيِّمُ السَّمَوَاتِ وَالأَرْضِ وَمَنْ فِيهِنَّ وَلَكَ الْحَمْدُ أَنْتَ الْحَقُّ وَوَعْدُكَ حَقٌّ وَقَوْلُكَ حَقٌّ وَلِقَاؤُكَ حَقٌّ وَالْجَنَّةُ حَقٌّ وَالنَّارُ حَقٌّ وَالسَّاعَةُ حَقٌّ وَالنَّبِيُّونَ حَقٌّ وَمُحَمَّدٌ حَقٌّ اللَّهُمَّ لَكَ أَسْلَمْتُ وَعَلَيْكَ تَوَكَّلْتُ وَبِكَ آمَنْتُ وَإِلَيْكَ أَنَبْتُ وَبِكَ خَاصَمْتُ وَإِلَيْكَ حَاكَمْتُ فَاغْفِرْ لِي مَا قَدَّمْتُ وَمَا أَخَّرْتُ وَمَا أَسْرَرْتُ وَمَا أَعْلَنْتُ أَنْتَ الْمُقَدِّمُ وَأَنْتَ الْمُؤَخِّرُ لاَ إِلَهَ إِلاَّ أَنْتَ أَوْ لاَ إِلَهَ غَيْرُكَ
