Sahih Muslim · Book 7: The Book of Prayer - Friday · The virtue of Friday
Abu Huraira reported the Messenger of Allah (ﷺ) as saying:
وَحَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ ، حَدَّثَنَا الْمُغِيرَةُ، - يَعْنِي الْحِزَامِيَّ - عَنْ أَبِي الزِّنَادِ ، عَنِ الأَعْرَجِ ، عَنْ أَبِي هُرَيْرَةَ ، أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ " خَيْرُ يَوْمٍ طَلَعَتْ عَلَيْهِ الشَّمْسُ يَوْمُ الْجُمُعَةِ فِيهِ خُلِقَ آدَمُ وَفِيهِ أُدْخِلَ الْجَنَّةَ وَفِيهِ أُخْرِجَ مِنْهَا وَلاَ تَقُومُ السَّاعَةُ إِلاَّ فِي يَوْمِ الْجُمُعَةِ " .
The best day on which the sun has risen is Friday; on it Adam was created. on it he was made to enter Paradise, on it he was expelled from it. And the last hour will take place on no day other than Friday.
