Hadith 3:233
Ibn ‘Umar reported God’s messenger as saying, “When any of you goes to the Friday prayer he should bathe.” (Bukhari and Muslim.)
عَنِ ابْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِذَا جَاءَ أَحَدُكُمُ الْجُمُعَةَ فَلْيَغْتَسِلْ»
