O Banu Bayādah, marry off (your daughters) to Abu Hind, and ask him to marry off (his daughters) to you

This Hadīth shows that the Prophet (may Allah's peace and blessings be upon him) had cupping made for him in his head by Abu Hind (may Allah be pleased with him). It also implies that suitability in family background and profession is not considered in marriage, for the Prophet (may Allah's peace and blessings be upon him) commanded Banu Bayādah, one of the Ansār tribes who belonged to the Azdi and Qahtāni Arabs, to marry their daughters off to Abu Hind and marry his daughters. Abu Hind was one of the freed slaves who belonged to Banu Bayādah, and beside being an ex-slave, his job was making cupping, which was a lowly profession in the sight of the Arabs. However, the Prophet (may Allah's peace and blessings be upon him) did not pay attention to suitability in family background or profession. Other texts indicate that suitability in religiousness and morals should be considered. Finally, the Prophet (may Allah's peace and blessings be upon him) mentioned that among the best methods of treatment is cupping.
