Sunan Ibn Majah, Volume 4, Book 32, Hadith 3565 (DarusSalam)

It was narrated that Anas bin Malik said: “I saw the Messenger of Allah marking sheep on their ears, and I saw him wearing a cloak around his wrist.”

حَدَّثَنَا سُوَيْدُ بْنُ سَعِيدٍ، حَدَّثَنَا مُوسَى بْنُ الْفَضْلِ، عَنْ شُعْبَةَ، عَنْ هِشَامِ بْنِ زَيْدٍ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ رَأَيْتُ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ يَسِمُ غَنَمًا فِي آذَانِهَا وَرَأَيْتُهُ مُتَّزِرًا بِكِسَاءٍ ‏.‏
