عَنْ أَبي هُرَيْرَةَ رَضِيَ اللهُ عَنْهُ
أَنَّ رَسُولَ اللهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ يَتنزَّلُ رَبُّنَا، تَبَارَكَ وَتَعَالَى، كُلَّ لَيْلَةٍ إلي سَمَاءِ الدُّنْيا، حينَ يَبْقَى ثُلُثُ اللَّيْلِ الاخِرُ، فَيَقُولُ: «مَنْ يَدْعُوني فأَسْتَجِيبَ لَه؟ مَنْ يَسْأَلُني فَأُعْطِيَهُ؟ مَنْ يَسْتَغْفِرُني فَأَغْفِرَلَهُ؟ وفي رواية لمسلم زيادة: فَلا يَزالُ كذَلِك حَتَى يُضِيءَ الفَجْرُ»
The Messenger of Allah (sallallahu alayhi wa sallam) said: Our Lord (glorified and exalted be He) descends each night to the earth’s sky when there remains the final third of the night, and He says: Who is saying a prayer to Me that I may answer it? Who is asking something of Me that I may give it him? Who is asking forgiveness of Me that I may forgive him?
It was related by al-Bukhari (also by Muslim, Malik, at-Tirmidhi and Abu Dawud). In a version by Muslim the Hadith ends with the words: And thus He continues till [the light of] dawn shines.
