سنن أبي داود#354Hasanحَدَّثَنَا أَبُو الْوَلِيدِ الطَّيَالِسِيُّ، حَدَّثَنَا هَمَّامٌ، عَنْ قَتَادَةَ، عَنِ الْحَسَنِ، عَنْ سَمُرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَنْ تَوَضَّأَ يَوْمَ الْجُمُعَةِ فَبِهَا وَنِعْمَتْ وَمَنِ اغْتَسَلَ فَهُوَ أَفْضَلُ " .
Narrated Samurah: If any one of you performs ablution (on Friday) that is all right; and if any of you takes a bath, that is better
