the Prophet said: "The best day that the sun has risen upon is Friday. On it Adam was created, on it he entered Paradise, and on it, he was expelled from it. And the Hour will not be established except on Friday."  

أَنَّ النَّبِيَّ ﷺ قَالَ خَيْرُ يَوْمٍ طَلَعَتْ فِيهِ الشَّمْسُ يَوْمُ الْجُمُعَةِ فِيهِ خُلِقَ آدَمُ وَفِيهِ أُدْخِلَ الْجَنَّةَ وَفِيهِ أُخْرِجَ مِنْهَا وَلاَ تَقُومُ السَّاعَةُ إِلاَّ فِي يَوْمِ الْجُمُعَةِ قَالَ وَفِي الْبَابِ عَنْ أَبِي لُبَابَةَ وَسَلْمَانَ وَأَبِي ذَرٍّ وَسَعْدِ بْنِ عُبَادَةَ وَأَوْسِ بْنِ أَوْسٍ
