It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) forbade that any townsman should sell the goods of a villager, or deceive in a sale, or that a man should send his marriage proposal over the proposal of his brother, or sell over the sale of his brother, and that a woman should not demand the divorce of her sister (whether real or religious) so that she may gather what is in her (sister’s) bowl or vessel for herself; rather, she should marry, for her sustenance is also the responsibility of Allah.
