Is a woman's request for a dowry (mahr), deferred dowry (mu'akhkhar), and a golden gift considered materialistic, and are these not among her rights?

The dowry is an obligatory right for the wife, as Allah Almighty says: "And give the women their dowries with a good heart." The dowry is a legal obligation, and it is not permissible for anyone after the Prophet, peace and blessings be upon him, to marry with a condition that there be no dowry. Waiving the dowry is forbidden, because it involves two rights: a right of Allah that cannot be waived, which is a quarter of a dinar or its equivalent, and a right of the wife. If the wife demands the dowry before consummation, the husband is compelled to pay it.
