Can a female neighbor who found an infant make her married daughters breastfeed this child so that he becomes her grandson through rada’a (nursing), and thus there would be no discomfort with him sitting with her in the house when he grows up, or is this considered a reprehensible trick? And does the neighbor’s daughter, whom my mother breastfed along with my brother, also become my sister, or only a sister to my brother who was nursed with her, in order to determine the extent of interaction with her and her sisters?
If one of your neighbor's daughters breastfeeds this child five times, he becomes her son through suckling, and your neighbor becomes his grandmother, and her daughters become his maternal aunts. He becomes a mahram to all of them. This is not a trick, but a lawful solution to remove hardship and enable the woman to raise and care for him, and she will be rewarded, based on the Prophet's (peace and blessings be upon him) saying: "Suckle him so that he becomes unlawful for you [in marriage]."
