(Imām Bukhārī narrates): Abdullah bin Yusuf narrated to us, he said: Imam Malik informed us, from Nafi', from Hazrat Abdullah bin Umar (may Allāh be pleased with them both), he narrates that the Messenger of Allāh ﷺ said:
When any one of you comes on the day of Friday, he should take a bath.
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، قَالَ أَخْبَرَنَا مَالِكٌ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا أَنَّ رسُولَ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ قَالَ
إِذَا جَاءَ أَحَدُكُمُ الجُمُعَةَ، فَلْيَغْتَسِلْ
