I want to marry off my daughter to my nephew but he was breastfed from his 60-year old grandmother.
(Part No. 21; Page No. 55) Although she said that a liquid similar to water was produced from her breast, she later claimed that nothing was produced from her breast out of her wish to establish a marital relation between them. It is noteworthy that she has been in her menopause for more than ten years. Please, tell us your Fatwa (legal opinion issued by a qualified Muslim scholar) as to whether it is permissible for my nephew to marry my daughter. May Allah reward you the best!
The breastfeeding mentioned in the above way has no effect. There is nothing wrong with your nephew getting married to your daughter, as the grandmother affirmed that the liquid which came out from her breast was water not milk, and that later she denied any liquid coming out from her at all.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
