Musnad Ahmad

It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that once he spent the night at the house of the Prophet (peace and blessings be upon him). The Prophet (peace and blessings be upon him) woke up during the night, used the miswak, performed ablution, and recited the last ten verses of Surah Al-Imran. Then he prayed two rak‘ahs in which he stood, bowed, and prostrated for a long time. After that, the Prophet (peace and blessings be upon him) lay down and slept until the sound of his snoring could be heard. Then he woke up and repeated the same actions, and this happened three times. After a short while, Sayyiduna Bilal (may Allah be pleased with him) came and informed him about the prayer, so the Prophet (peace and blessings be upon him) went to lead the prayer, and in prostration, the Prophet (peace and blessings be upon him) began to supplicate: «اَللّٰهُمَّ اجْعَلْ فِي قَلْبِي نُورًا وَاجْعَلْ فِي سَمْعِي نُورًا وَاجْعَلْ فِي بَصَرِي نُورًا وَاجْعَلْ أَمَامِي نُورًا وَخَلْفِي نُورًا وَاجْعَلْ عَنْ يَمِينِي نُورًا وَعَنْ شِمَالِي نُورًا وَفَوْقِي نُورًا وَتَحْتِي نُورًا اَللّٰهُمَّ أَعْظِمْ لِي نُورًا» "O Allah! Place light in my heart, in my ears, in my eyes, on my right, on my left, in front of me, behind me, above me, and beneath me, and grant me more and more light."
