Hadith Qudsi 35
Compile by Imam Nawawi: Translated by Ezzeddin Ibrahim & Denys Johnson-Davies

On the authority of Abu Hurayrah (may Allah be pleased with him), who said that the Messenger of Allah (peace and blessings of Allah be upon him) 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."
