"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 وَكُنْتُ إِذَا نَظَرْتُ إِلَيْهِ قُلْتُ أَكْحَلُ الْعَيْنَيْنِ وَلَيْسَ بِأَكْحَلَ» وَاللَّفْظُ لِحَدِيثِ عَبْدِ الرَّحْمَنِ بْنِ عُبَيْدِ اللهِ
