Sayyiduna Salamah bin al-Akwa' (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) had a slave called Yasar. He (peace and blessings be upon him) saw him praying well, so he freed him and sent him to his milch camels in the area of al-Harrah, where he stayed. Meanwhile some people of the tribe of Uraynah, who were from Yemen, came professing Islam; they were sick and feverish, and their bellies had become swollen. So the Prophet (peace and blessings be upon him) sent them to Yasar, and they kept drinking the camels' milk until their bellies recovered. Then they attacked Yasar and slaughtered him, and drove thorns into his eyes, then drove off the camels. The Prophet (peace and blessings be upon him) sent some Muslim horsemen in pursuit of them, whose commander was Kurz bin Jabir al-Fihri. He caught up with them and brought them back, and then their hands and feet were cut off and their eyes were put out.
