Jami` at-Tirmidhi, Volume 6, Book 46, Hadith 3645 (DarusSalam) ⓘ
Narrated Jabir bin Samurah: "The two shins of the Messenger of Allah were thin, and he would not laugh except as a smile, and whenever I looked at him I would say: "He put kohl on his eyes,' but he did not use kohl."
حَدَّثَنَا أَحْمَدُ بْنُ مَنِيعٍ، حَدَّثَنَا عَبَّادُ بْنُ الْعَوَّامِ، أَخْبَرَنَا الْحَجَّاجُ، هُوَ ابْنُ أَرْطَاةَ عَنْ سِمَاكِ بْنِ حَرْبٍ، عَنْ جَابِرِ بْنِ سَمُرَةَ، قَالَ كَانَ فِي سَاقَىْ رَسُولِ اللَّهِ صلى الله عليه وسلم حُمُوشَةٌ وَكَانَ لاَ يَضْحَكُ إِلاَّ تَبَسُّمًا وَكُنْتُ إِذَا نَظَرْتُ إِلَيْهِ قُلْتُ أَكْحَلَ الْعَيْنَيْنِ وَلَيْسَ بِأَكْحَلَ . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ غَرِيبٌ مِنْ هَذَا الْوَجْهِ .
