Mukhtasar Muslim

Ja'far bin Amr bin Umayyah al-Damri narrates from his father, Sayyiduna Amr bin Umayyah al-Damri (may Allah be pleased with him), that he said: I saw the Messenger of Allah (peace and blessings be upon him) cutting and eating the shoulder of a goat with a knife. In the meantime, he was called for prayer, so the Prophet (peace and blessings be upon him) put down the knife, performed the prayer, and did not perform ablution.
