Are the mother's reasons for rejecting the suitor intending to marry her eldest daughter—namely, that he is divorced and has a child, that his brother did not fulfill a marriage proposal, and that the reason for his divorce from his first wife is not valid—considered legitimate reasons that necessitate rejecting him and not approving of him?

If the suitor is righteous and the sister is pleased with him, then the guardian (wali) or the mother does not have the right to prevent her from marrying him. The reasons for rejection mentioned by the mother, such as the man being divorced, are not religiously acceptable. Marrying a virgin to a divorced man is better than leaving her without marriage. It is advised to accept the suitor, to gently persuade the mother, and to involve wise individuals to convince her.
