أَخْبَرَنَا قُتَيْبَةُ، عَنْ مَالِكٍ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ إِذَا جَاءَ أَحَدُكُمُ الْجُمُعَةَ فَلْيَغْتَسِلْ .
It was narrated from Ibn 'Umar that: The Messenger of Allah (ﷺ) said: "When any one of you wants to come to Jumu'ah prayer, let him perform ghusl."
