It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: No man should send a marriage proposal over the proposal of his brother, nor should he bargain over the bargain of his brother, nor should a woman be married (to a man) while her paternal aunt or maternal aunt is married to him, and no woman should demand the divorce of her sister (whether real or religious) so that she may gather what is in her bowl or vessel for herself; rather, she should marry, for her sustenance is also the responsibility of Allah.
