It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) forbade marrying a woman and her paternal aunt together, or a woman and her niece together, or a woman and her maternal aunt together, or a woman and her niece together. And the Prophet (peace and blessings be upon him) also forbade marrying the younger over the elder, and the elder over the younger.
