Allah waits till when one-third of the first part of the night is over; He descends to the lowest heaven and says: It there any supplicator of forgiveness? Is there any penitant? Is there any petitioner (for mercy and favour)? Is there any solicitor? -till it is daybreak.  

قَالَ رَسُولُ اللَّهِ ﷺ إِنَّ اللَّهَ يُمْهِلُ حَتَّى إِذَا ذَهَبَ ثُلُثُ اللَّيْلِ الأَوَّلُ نَزَلَ إِلَى السَّمَاءِ الدُّنْيَا فَيَقُولُ هَلْ مِنْ مُسْتَغْفِرٍ هَلْ مِنْ تَائِبٍ هَلْ مِنْ سَائِلٍ هَلْ مِنْ دَاعٍ حَتَّى يَنْفَجِرَ الْفَجْرُ  

[Machine] The Messenger of Allah ﷺ said: "Verily, Allah delays until the first third of the night passes, then our Lord, blessed and exalted, descends to the lowest heaven and says, 'Is there anyone seeking forgiveness, so that I may forgive them? Is there any repentant, so that I may accept their repentance? Is there any seeker, so that I may grant them? Is there any supplicant, so that I may answer their supplication?' This continues until dawn breaks."  

قَالَ رَسُولُ اللَّهِ ﷺ «إِنَّ اللَّهَ يُمْهِلُ حَتَّى إِذَا ذَهَبَ ثُلُثُ اللَّيْلِ الْأَوَّلُ نَزَلَ رَبُّنَا تَبَارَكَ وَتَعَالَى إِلَى السَّمَاءِ الدُّنْيَا فَيَقُولُ جَلَّ وَعَلَا هَلْ مِنْ مُسْتَغْفِرٍ؟ هَلْ مِنْ تَائِبٍ؟ هَلْ مِنْ سَائِلٍ؟ هَلْ مِنْ دَاعٍ؟ حَتَّى يَنْفَجِرَ الصُّبْحُ»
