عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ، عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم قَالَ
يَوْمُ الْجُمُعَةِ اثْنَتَا عَشْرَةَ سَاعَةً لاَ يُوجَدُ فِيهَا عَبْدٌ مُسْلِمٌ يَسْأَلُ اللَّهَ شَيْئًا إِلاَّ آتَاهُ إِيَّاهُ فَالْتَمِسُوهَا آخِرَ سَاعَةٍ بَعْدَ الْعَصْرِ
رواه النسائي ١٣٩٠ وصححه الألبني
It was narrated from Jabir bin ‘Abdullah that:
The Messenger of Allah (ﷺ) said:
“Friday is twelve hours in which there is no Muslim slave who asks Allah (SWT) for something but He will give it to him, so seek it in the last hour after ‘Asr.”
Sunan an-Nasai, 1390 and Al-Albani classed it as Saheeh.
