حَدَّثَنَا يُوسُفُ بْنُ عِيسَى، قَالَ‏:‏ حَدَّثَنَا وَكِيعٌ، قَالَ‏:‏ حَدَّثَنَا الرَّبِيعُ بْنُ صَبِيحٍ، عَنْ يَزِيدَ بْنِ أَبَانَ هُوَ الرَّقَاشِيُّ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ‏:‏ كَانَ رَسُولُ اللهِ صلى الله عليه وسلم يُكْثِرُ دَهْنَ رَأْسِهِ وَتَسْرِيحَ لِحْيَتِهِ، وَيُكْثِرُ الْقِنَاعَ حَتَّى كَأَنَّ ثَوْبَهُ، ثَوْبُ زَيَّاتٍ‏.‏
Translation
Anas ibn Malik said

“Allah’s Messenger (Allah bless him and give him peace) made a frequent practice of oiling his head and combing his beard, and he often wore the head veil, so it was as if hisrobe was the robe of an oil dealer.”
