The Prophet ﷺ said: Friday is divided into twelve hours. Amongst them there is an hour in which a Muslim does not ask Allah for anything but He gives it to him. So seek it in the last hour after the afternoon prayer.
عَنْ رَسُولِ اللَّهِ ﷺ أَنَّهُ قَالَ يَوْمُ الْجُمُعَةِ ثِنْتَا عَشْرَةَ يُرِيدُ سَاعَةً لاَ يُوجَدُ مُسْلِمٌ يَسْأَلُ اللَّهَ ﷻ شَيْئًا إِلاَّ آتَاهُ اللَّهُ ﷻ فَالْتَمِسُوهَا آخِرَ سَاعَةٍ بَعْدَ الْعَصْرِ
