The Messenger of Allah ﷺ said, "Whoever bathes on Friday, puts on his finest clothes, applies perfume if he has any, then comes to the Friday prayer without stepping over people's necks, then prays whatever Allah has decreed for him, then listens silently when his imam comes out until he finishes the prayer, this will be an expiation for what is between it and the previous Friday."Abu Hurairah used to add, "And three days more," and he would say, "For a good deed is rewarded tenfold."
قال رسول الله ﷺ: من اغتسل يوم الجمعة، ولبس من أحسن ثيابه ومس من طيب إن كان عنده، ثم أتى الجمعة، فلم يتخط أعناق الناس، ثم صلى ما كتب الله له، ثم أنصت إذا خرج إمامه حتى يفرغ من صلاته، كانت كفارة لما بينها وبين جمعته التي قبلها. قال: ويقول أبو هريرة: وزيادة ثلاثة أيام. ويقول: إن الحسنة بعشر أمثالها.
Reported by Abu Dawud (343) and Ahmad (11768), and Ibn Khuzayma (1762) and Hakim (1/283) graded it sahih, all of them through routes from Muhammad bin Ishaq, who said, Muhammad bin Ibrahim narrated to me, from Abu Salama bin Abdul-Rahman and Abu Umama bin Sahl, from Abu Saeed Khudri and Abu Hurairah, and they related the hadith.Its chain is hasan, for Muhammad bin Ishaq's hadith is hasan when he states his source explicitly.
