صَحِيحُ مُسْلِمٍ
Sahih Muslim 757 b
The Book of Prayer - Travellers
In the night there is an hour when supplications are answered
وَحَدَّثَنِي سَلَمَةُ بْنُ شَبِيبٍ، حَدَّثَنَا الْحَسَنُ بْنُ أَعْيَنَ، حَدَّثَنَا مَعْقِلٌ، عَنْ أَبِي الزُّبَيْرِ، عَنْ جَابِرٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ إِنَّ مِنَ اللَّيْلِ سَاعَةً لاَ يُوَافِقُهَا عَبْدٌ مُسْلِمٌ يَسْأَلُ اللَّهَ خَيْرًا إِلاَّ أَعْطَاهُ إِيَّاهُ .
Jabir reported: I heard the Messenger of Allah (ﷺ) as saying: There is an hour during the night in which no Muslim bondman will ask Allah for good in this world and the next but He will grant it to him.
