Yunus bin Maisarah bin Halbas said: “I went out with Abu Sa’eed Az- Zuraqi, the Companion of the Messenger of Allah (ﷺ), to buy animals or sacrifice.” Yunus said: “Abu Sa’eed pointed to a ram that had some blackness around its ears and jaw, and was neither too big nor too small, and said to me: ‘Buy this one for them, as it seems to resemble the ram of the Messenger of Allah (ﷺ).’”
It was narrated from Abu Umamah Al-Bahili that the Messenger of Allah (ﷺ) said: “The best of shrouds is a two piece Najrani garment and the best of sacrifices is a horned ram.”
