Sahih Muslim , Book 4, Hadith 1850 (USC-MSA) ⓘ

Abu Huraira reported Abu'l-Qasim (the kunya of the Holy Prophet) as saying: There is a time on Friday at which no Muslim would stand and pray and beg Allah for what Is good but He would give it to him; and he pointed with his hand that (this time) is short and narrow.

حَدَّثَنَا زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا إِسْمَاعِيلُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا أَيُّوبُ، عَنْ مُحَمَّدٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ أَبُو الْقَاسِمِ صلى الله عليه وسلم ‏ "‏ إِنَّ فِي الْجُمُعَةِ لَسَاعَةً لاَ يُوَافِقُهَا مُسْلِمٌ قَائِمٌ يُصَلِّي يَسْأَلُ اللَّهَ خَيْرًا إِلاَّ أَعْطَاهُ إِيَّاهُ." وَقَالَ بِيَدِهِ يُقَلِّلُهَا يُزَهِّدُهَا.
