Giving the first wife Mahr upon marrying a second one

Q: A married man got married for the second time. His first wife asked him to give her as much jewels as he gives the second wife. Is it obligatory on him to do that?

A: He is not required to give his first wife as much as he gives his second wife with regard to dowry and other things. But if he gives her things similar to that which he gives his second wife in order to satisfy her, it will be good. Moreover, it will be better for him to do this if he desires to deal leniently with her in the future. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
