The slaughtering of sacrificial animals (Hady) during Hajj is one of the sacred rites through which closeness to Allah is sought.In this Hadith, the Mother of the Believers, `A’ishah (may Allah be pleased with her), informs us that the Messenger of Allah (peace and blessings of Allah be upon him) slaughtered "on behalf of his household", meaning, he offered a sacrificial animal either specifically on behalf of `A’ishah (may Allah be pleased with her) alone or on behalf of all his wives, “during the Farewell Hajj”, which occurred shortly before his passing and thus served as a final parting gesture to his Companions (may Allah be pleased with them). He offered "one cow," indicating that a single cow was sacrificed on behalf of his wives (may Allah be pleased with them) or of `A’ishah (may Allah be pleased with her) in particular.This Hadith demonstrates the permissibility of offering a cow as part of the sacrifice during Hajj..
