(6) باب الدُّهْنِ لِلْجُمُعَةِ
Narrated Tawus:
I said to Ibn `Abbas, "The people are narrating that the Prophet (ﷺ) said, 'Take a bath on Friday and wash your heads (i.e. take a thorough bath) even though you were not Junub and use perfume'." On that Ibn `Abbas replied, "I know about the bath, (i.e. it is essential) but I do not know about the perfume (i.e. whether it is essential or not.)
