Hadith 1146

نَا نَا مُحَمَّدُ بْنُ بَشَّارٍ ، نَا مُحَمَّدُ بْنُ جَعْفَرٍ ، قَالَ : حَدَّثَنَا شُعْبَةُ ، عَنْ أَبِي إِسْحَاقَ ، عَنِ الأَغَرِّ ، قَالَ : أَشْهَدُ عَلَى أَبِي هُرَيْرَةَ ، وَأَبِي سَعِيدٍ الْخُدْرِيِّ أَنَّهُمَا شَهِدَا عَلَى رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ : " إِنَّ اللَّهَ يُمْهِلُ حَتَّى يَذْهَبَ ثُلُثُ اللَّيْلِ فَيَنْزِلُ ، فَيَقُولُ : هَلْ مِنْ سَائِلٍ ؟ هَلْ مِنْ تَائِبٍ ؟ هَلْ مِنْ مُسْتَغْفِرٍ مِنْ ذَنْبٍ ؟ " ، فَقَالَ لَهُ رَجُلٌ : حَتَّى مَطْلَعِ الْفَجْرِ ؟ قَالَ : " نَعَمْ "
Sayyiduna Abu Hurairah and Sayyiduna Abu Sa'id Khudri (may Allah be pleased with them) bear witness regarding the Messenger of Allah (peace and blessings be upon him) that he said: "Indeed, Allah gives respite until a third of the night has passed. Then He descends (to the lowest heaven) and says: 'Is there anyone who asks, so that I may give him? Is there anyone who repents, so that I may accept his repentance? Is there anyone who seeks forgiveness for sins, so that I may forgive him?'" A man asked the Prophet (peace and blessings be upon him): "Does this (series of mercy and blessings) continue until the break of dawn?" The Prophet (peace and blessings be upon him) replied: "Yes."
