Abu Hurairah reported the Prophet ﷺ as saying; Our lord gets down every night to the heaven of this world when a third night remains and says :
(Is there anyone) who prays to Me so that I may accept his prayer? (Is there anyone) who asks of Me so that I may give him? (Is there anyone) who asks for my forgiveness so that I may forgive him?

حَدَّثَنَا الْقَعْنَبِيُّ، عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، عَنْ أَبِي سَلَمَةَ بْنِ عَبْدِ الرَّحْمَنِ، وَعَنْ أَبِي عَبْدِ اللَّهِ الأَغَرِّ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ " يَنْزِلُ رَبُّنَا كُلَّ لَيْلَةٍ إِلَى سَمَاءِ الدُّنْيَا حِينَ يَبْقَى ثُلُثُ اللَّيْلِ الآخِرِ فَيَقُولُ مَنْ يَدْعُونِي فَأَسْتَجِيبَ لَهُ مَنْ يَسْأَلُنِي فَأُعْطِيَهُ مَنْ يَسْتَغْفِرُنِي فَأَغْفِرَ لَهُ " .
