Sunan an-Nasa'i 1376
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."
أَخْبَرَنَا قُتَيْبَةُ، عَنْ مَالِكٍ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏
"‏ إِذَا جَاءَ أَحَدُكُمُ الْجُمُعَةَ فَلْيَغْتَسِلْ ‏"‏ ‏.‏
