Appearing Of The White Hair Of Rasoolullah
Ash-Shama'il Al-Muhammadiyah 39
Jabir ibn Samura was asked about the grayness of Allah’s Messenger (Allah bless him and give him peace), so he said:
"When he oiled his head, no grayness was visible, and when he did not apply oil, some was visible.”
حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، قَالَ‏:‏ أَخْبَرَنَا أَبُو دَاوُدَ، قَالَ‏:‏ حَدَّثَنَا شُعْبَةُ، عَنْ سِمَاكِ بْنِ حَرْبٍ، قَالَ‏:‏ سَمِعْتُ جَابِرَ بْنَ سَمُرَةَ، وَقَدْ سُئِلَ عَنْ شَيْبِ رَسُولِ اللهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّم، فَقَالَ‏:‏ كَانَ إِذَا دَهَنَ رَأْسَهُ لَمْ يُرَ مِنْهُ شَيْبٌ، وَإِذَا لَمْ يَدْهِنْ رُئِيَ مِنْهُ شَيْءٌ‏.‏
