باب السَّاعَةِ الَّتِي فِي يَوْمِ الْجُمُعَةِ

Narrated Abu Huraira:

Allah's Messenger (ﷺ) (p.b.u.h) talked about Friday and said, "There is an hour (opportune time) on Friday and if a Muslim gets it while praying and asks something from Allah, then Allah will definitely meet his demand." And he (the Prophet) pointed out the shortness of that time with his hands.

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ، عَنْ مَالِكٍ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم ذَكَرَ يَوْمَ الْجُمُعَةِ فَقَالَ ‏ "‏ فِيهِ سَاعَةٌ لاَ يُوَافِقُهَا عَبْدٌ مُسْلِمٌ، وَهْوَ قَائِمٌ يُصَلِّي، يَسْأَلُ اللَّهَ تَعَالَى شَيْئًا إِلاَّ أَعْطَاهُ إِيَّاهُ ‏"‏‏.‏ وَأَشَارَ بِيَدِهِ يُقَلِّلُهَا‏.‏
