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. (Using translation from Muslim 854a)  

قَالَ رَسُولُ اللهِ ﷺ «خَيْرُ يَوْمٍ طَلَعَتْ عَلَيْهِ الشَّمْسُ يَوْمُ الْجُمُعَةِ فِيهِ خُلِقَ آدَمُ وَفِيهِ أُدْخِلَ الْجَنَّةَ وَفِيهِ أُخْرِجَ مِنْهَا»  

"The Messenger of Allah ﷺ said to me: 'There is no man who purifies himself on Friday as he is commanded, then comes out of his house to the Friday prayer, and listens attentively until he finishes his prayer, but it will be an expiation for what came before it the week before." (Using translation from Nasāʾī 1403)   

قَالَ لِي رَسُولُ اللهِ ﷺ «مَا مِنْ رَجُلٍ يَتَطَهَّرُ يَوْمَ الْجُمُعَةِ كَمَا أُمِرَ ثُمَّ يَخْرُجُ مِنْ بَيْتِهِ حَتَّى يَأْتِيَ الْجُمُعَةَ فَيُنْصِتَ حَتَّى يَقْضِيَ الْإِمَامُ صَلَاتَهُ إِلَّا كَانَ كَفَّارَةً لِمَا كَانَ قَبْلَهُ مِنَ الْجُمُعَةِ»  

[Machine] The Messenger of Allah ﷺ said, "Do you know what day Friday is?" I said, "Allah and His Messenger know best." He said, "However, I will tell you about Friday. If a man performs ablution and goes to the Friday prayer and listens attentively until the imam finishes his prayer, it will be an expiation for the sins committed between that Friday and the previous one, and will also prevent him from the temptation of killing."  

قَالَ رَسُولُ اللهِ ﷺ «أَتَدْرِي مَا يَوْمُ الْجُمُعَةِ؟» قُلْتُ اللهُ وَرَسُولُهُ أَعْلَمُ قَالَ «لَكِنِّي أَنَا أُحَدِّثُكَ عَنْ يَوْمِ الْجُمُعَةِ لَا يَتَطَهَّرُ رَجُلٌ ثُمَّ يَمْشِي إِلَى الْجُمُعَةِ ثُمَّ يُنْصِتُ حَتَّى يَقْضِيَ الْإِمَامُ صَلَاتَهُ إِلَّا كَانَتْ كَفَّارَةً لِمَا بَيْنَهَا وَبَيْنَ الْجُمُعَةِ الَّتِي قَبْلَهَا مَا اجْتُنِبَتِ الْمَقْتَلَة»
