Messenger of Allah (S) said: "Allah, Blessed and Exalted is He, descends to the earth's heaven every night when the first third of the night has passed. He says: "I am the Sovereign. Is there any who calls upon Me so that I may respond to him? Is there any who asks of Me that I may give him? Is there any who seeks forgiveness from Me so that I may forgive him?' He continues in that until the illumination of Al-Fajr."
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ يَنْزِلُ اللَّهُ إِلَى السَّمَاءِ الدُّنْيَا كُلَّ لَيْلَةٍ حِينَ يَمْضِي ثُلُثُ اللَّيْلِ الأَوَّلُ فَيَقُولُ أَنَا الْمَلِكُ مَنْ ذَا الَّذِي يَدْعُونِي فَأَسْتَجِيبَ لَهُ مَنْ ذَا الَّذِي يَسْأَلُنِي فَأُعْطِيَهُ مَنْ ذَا الَّذِي يَسْتَغْفِرُنِي فَأَغْفِرَ لَهُ فَلاَ يَزَالُ كَذَلِكَ حَتَّى يُضِيءَ الْفَجْرُ قَالَ وَفِي الْبَابِ عَنْ عَلِيِّ بْنِ أَبِي طَالِبٍ وَأَبِي سَعِيدٍ وَرِفَاعَةَ الْجُهَنِيِّ وَجُبَيْرِ بْنِ مُطْعِمٍ وَابْنِ مَسْعُودٍ وَأَبِي الدَّرْدَاءِ وَعُثْمَانَ بْنِ أَبِي الْعَاصِ
