Hadith 12:372
Shababa narrated to us, he said: Shu'bah narrated to us, from Hisham bin Zayd, he said: I heard Anas bin Malik saying: I saw the Messenger of Allah, peace and blessings of Allah be upon him, while he was in the *mirbad* (enclosure), branding some sheep of his. I think he said: in their ears.
حدثنا شبابة قال نا شعبة عن هشام بن زيد قال سمعت أنس بن مالك يقول رأيت رسول الله صلى الله عليه وسلم وهو في المربد يسم غنما له أحسبه قال في آذانها
