Sayyiduna al-Sunabihi al-Ahmasi (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him) saw a fine, full-grown she-camel among the zakah camels; he (peace and blessings be upon him) became angry and said: "May Allah destroy the owner of this she-camel." He (the collector) said: O Messenger of Allah! I took it in exchange for two camels. He (peace and blessings be upon him) said: "Then that is fine."
Abu Isa (may Allah have mercy on him) said: I asked Imam al-Bukhari (may Allah have mercy on him) about it, and he said that Isma'il bin Abi Khalid narrated this hadith from Qays bin Abi Hazim that the Prophet (peace and blessings be upon him) saw (it) among the zakah camels, as mursal; and he declared Mujalid weak.
