Ad-Dahn (Oil)

It was narrated that Simak said:

"I heard Jabir bin Samurah being asked about the gray hairs of the Prophet ﷺ. He said: 'If he put oil on his head they could not be seen, but if he did not put oil on his head, they could be seen.'"

أَخْبَرَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، قَالَ حَدَّثَنَا أَبُو دَاوُدَ، قَالَ حَدَّثَنَا شُعْبَةُ، عَنْ سِمَاكٍ، قَالَ سَمِعْتُ جَابِرَ بْنَ سَمُرَةَ، سُئِلَ عَنْ شَيْبِ، رَسُولِ اللَّهِ ﷺ قَالَ كَانَ إِذَا ادُّهِنَ رَأْسُهُ لَمْ يُرَ مِنْهُ وَإِذَا لَمْ يُدَّهَنْ رُئِيَ مِنْهُ .
