Sayyiduna Abu Hurairah (may Allah be pleased with him) narrated that the Messenger of Allah (peace and blessings be upon him) forbade marrying a woman and her paternal niece together, or a niece and her paternal aunt together; likewise, marrying a woman and her maternal niece together, or a niece and her maternal aunt together. Neither should the elder be married along with the younger, nor the younger along with the elder.
