باب فِي السَّاعَةِ الَّتِي فِي يَوْمِ الْجُمُعَةِ ‏

Abu Huraira reported Allah's Apostle (ﷺ) as saying:

"There is a time on Friday at which no Muslim would ask Allah for what is good but He would give it to him." And further said: "This is a very short time."
وَحَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ سَلاَّمٍ الْجُمَحِيُّ، حَدَّثَنَا الرَّبِيعُ، - يَعْنِي ابْنَ مُسْلِمٍ - عَنْ مُحَمَّدِ بْنِ زِيَادٍ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم أَنَّهُ قَالَ ‏ "‏ إِنَّ فِي الْجُمُعَةِ لَسَاعَةً لا يُوَافِقُهَا مُسْلِمٌ يَسْأَلُ اللَّهَ فِيهَا خَيْرًا إِلاَّ أَعْطَاهُ إِيَّاهُ ‏"‏ ‏.‏ قَالَ وَهِيَ سَاعَةٌ خَفِيفَةٌ
