Hadith 4068
Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates: The Noble Prophet (peace and blessings be upon him) said: "A woman should not be married together with her paternal aunt or her maternal aunt (i.e., one should not marry a woman along with her niece), and no woman should demand the divorce of her sister (i.e., co-wife) so that she may obtain what is in her vessel, for she will only get what has been decreed for her."
