It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) marked his sacrificial animal (hady) with ish'ar (making a cut in its hump as a sign) and hung a garland (qiladah) around its neck.
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from al-Ala' bin al-Musayyib except Qays, and no one narrated it from Qays except Waki'; Sufyan bin Waki' is alone in narrating it."
