Hadith: He who performs ablution properly and then comes to the Friday prayer and listens to it attentively and keeps silent, his sins between that Friday and the following Friday will be forgiven, with the addition of three more days

عَنْ أَبِي هُرَيْرَةَ رضي الله عنه قَالَ: قَالَ رَسُولُ اللهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ:
«مَنْ تَوَضَّأَ فَأَحْسَنَ الْوُضُوءَ ثُمَّ أَتَى الْجُمُعَةَ فَاسْتَمَعَ وَأَنْصَتَ غُفِرَ لَهُ مَا بَيْنَهُ وَبَيْنَ الْجُمُعَةِ وَزِيَادَةُ ثَلَاثَةِ أَيَّامٍ، وَمَنْ مَسَّ الْحَصَى فَقَدْ لَغَا».
[صحيح] - [رواه مسلم] - [صحيح مسلم: 857]

Abu Hurayrah (may Allah be pleased with him) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) said:
"He who performs ablution properly and then comes to the Friday prayer and listens to it attentively and keeps silent, his sins between that Friday and the following Friday will be forgiven, with the addition of three more days; but he who touches a pebble has engaged in idle activity."
[Authentic hadith] - [Narrated by Muslim] - [Sahih Muslim - 857]

Explanation

The Prophet (may Allah's peace and blessings be upon him) informs that if a Muslim performs ablution properly, fulfilling its obligatory elements and observing its Sunnahs and etiquettes, and then goes to the Friday prayer and listens attentively to the preacher, refraining from idle activity, Allah will forgive for him the minor sins committed in ten days, from this Friday prayer to the next Friday prayer, in addition to three days. This is because the reward for a good deed is multiplied tenfold. Then, he (may Allah's peace and blessings be upon him) warned about the lack of attention to the admonitions given in the sermon and any physical diversion, like touching the pebbles and so on, saying that whoever does so has engaged in idle activity, and whoever engages in idle activity does not attain the complete reward of Friday prayer.
