"The two shins of the Messenger of Allah ﷺ 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 ﷺ did not use kohl." (Using translation from Tirmidhī 3645)
كَانَ فِي سَاقَيْ رَسُولِ اللهِ ﷺ حُمُوشَةٌ وَكَانَ لَا يَضْحَكُ إِلَّا تَبَسُّمًا وَكَانَ إِذَا نَظَرْتُ إِلَيْهِ قُلْتُ أَكْحَلُ وَلَيْسَ بِأَكْحَلَ
