Muwatta Imam Malik Book of Jumu'a, Hadith 4

Yahya related to me from Malik from Safwan ibn Sulaym from Ata ibn Yasar from Abu Said al-Khudri that the Messenger of Allah ﷺ said, "Ghusl on the day of jumua is incumbent on every male who has reached puberty."

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ صَفْوَانَ بْنِ سُلَيْمٍ، عَنْ عَطَاءِ بْنِ يَسَارٍ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ " غُسْلُ يَوْمِ الْجُمُعَةِ وَاجِبٌ عَلَى كُلِّ مُحْتَلِمٍ " .
