It was narrated that Abu Hurairah said:
“The Messenger of Allah ﷺ said: ‘On Friday there is a time when no Muslim man happens to stand in prayer at that time, asking Allah for good things, but He will give that to him.” And he gestured with his hand to indicate how short that time is.

حَدَّثَنَا مُحَمَّدُ بْنُ الصَّبَّاحِ، أَنْبَأَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنْ أَيُّوبَ، عَنْ مُحَمَّدِ بْنِ سِيرِينَ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ ﷺ " إِنَّ فِي الْجُمُعَةِ سَاعَةً لاَ يُوَافِقُهَا رَجُلٌ مُسْلِمٌ قَائِمٌ يُصَلِّي يَسْأَلُ اللَّهَ فِيهَا خَيْرًا إِلاَّ أَعْطَاهُ " . وَقَلَّلَهَا بِيَدِهِ .
