وَعَنْ أَبِي هُرَيْرَةَ – رضى الله عنه – قَالَ: قَالَ رَسُولُ اَللَّهِ – صلى الله عليه وسلم -{ مَنِ اغْتَسَلَ, ثُمَّ أَتَى الْجُمُعَةَ, فَصَلَّى مَا قُدِّرَ لَهُ, ثُمَّ أَنْصَتَ, حَتَّى يَفْرُغَ اَلْإِمَامُ مِنْ خُطْبَتِهِ, ثُمَّ يُصَلِّي مَعَهُ: غُفِرَ لَهُ مَا بَيْنَهُ وَبَيْنَ الْجُمُعَةِ اَلْأُخْرَى, وَفَضْلُ ثَلَاثَةِ أَيَّامٍ } رَوَاهُ مُسْلِم ٌ 1 . 1 – صحيح. رواه مسلم (857) (27).

Narrated Abu Hurairah (RA): Allah’s Messenger (صلى الله عليه وسلم) said: “Whoever takes a bath, then comes to al-Jumu’ah prayer, then prays what was fixed for him, then keeps silent till the Imam finishes the Khutbah (religious talk – sermon), and then prays along with him – his sins (committed) between that time and the next Friday will be forgiven, with an addition of three days more.” [Reported by Muslim].
