A special time-window on Fridays for the acceptance of prayers

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.‏

Hazrat Abu Hurairah^ra narrated: 

“Allah’s Messenger^sa said, ‘There is time-window on Fridays; should a Muslim encounter it while standing in salat and supplicating, Allah the Exalted will surely grant his request.’ He then gestured with his hand to indicate how brief it is.”
