Mishkat al-Masabih 1223
Abu Huraira reported God’s Messenger as saying:
Our Lord who is blessed and exalted descends every night to the lowest heaven when two-thirds of the night have passed and says, “Who supplicates me so that I may answer him? Who asks of me so that I may give to him? Who asks my forgiveness so that I may forgive him?” 

(Bukhari and Muslim.) In a version by Muslim it is said that He then spreads out His hands and says, “Who will lend to One who is neither indigent nor unjust?"* till the dawn breaks.
*The lending mentioned here is presumably the doing of good works.
وَعَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: 
" يَنْزِلُ رَبُّنَا تَبَارَكَ وَتَعَالَى كُلَّ لَيْلَةٍ إِلَى السَّمَاءِ الدُّنْيَا حِينَ يَبْقَى ثُلُثُ اللَّيْلِ الْآخِرُ يَقُولُ: مَنْ يَدْعُونِي فَأَسْتَجِيبَ لَهُ؟ مَنْ يَسْأَلُنِي فَأُعْطِيَهُ؟ مَنْ يَسْتَغْفِرُنِي فَأَغْفِرَ لَهُ؟ "
وَفِي رِوَايَةٍ لِمُسْلِمٍ: ثُمَّ يَبْسُطُ يَدَيْهِ وَيَقُولُ: «مَنْ يُقْرِضُ غَيْرَ عَدُومٍ وَلَا ظَلُومٍ؟ حَتَّى ينفجر الْفجْر»
