It is narrated from Sayyiduna Abu Musa (may Allah be pleased with him) that he said: When the Prophet (peace and blessings be upon him) had finished with Hunayn, he sent Abu Amir (may Allah be pleased with him) in command of the army to Awtas. He met Durayd bin al-Simmah; Durayd was killed and Allah defeated his companions.
