Mahr
Mahr is a gift from the groom to the bride, obligatory and owed to her personally — not to her family. It can be paid in full before the nikah (muqaddam) or deferred (mu'akhkhar), typically in the case of divorce or death.
There is no fixed amount in the Qur'an. The sunnah is to keep mahr reasonable and within the groom's means. The blessing, as the Prophet ﷺ taught, is in the marriage that is not burdened by excess.
Discuss mahr with her and her wali openly before the nikah. Unclear or unfulfilled mahr is a common source of regret and disputes later — settle it properly up front.
Shared expenses after marriage
In Islamic jurisprudence, nafaqah (household maintenance) is the husband's responsibility: housing, food, basic clothing, healthcare.
In practice today, many couples discuss a shared approach — who covers what, how they save together, how they handle her earnings (which remain hers unless she chooses to contribute).
The principle: the husband's obligation to provide doesn't disappear just because she also earns. Her earnings are her own. His provision is his duty.
Saving for a home
If you're not ready to house a wife, you may not be ready to marry. That doesn't mean you need to own a home — renting is valid and historically normal — but you need a plan.
Practical questions to answer before you're seriously approaching sisters:
Debt and riba
Student loans, credit card balances, and consumer debt are real considerations. Islam takes a serious view of riba (interest). If you're carrying interest-bearing debt, have a plan to exit it — and be honest about it with her and her wali.
It's not automatically a disqualifier. Hidden debt is far worse than known debt.
A simple readiness check
If you could not, today, cover: mahr you've agreed, rent on a modest place for two, food and basic expenses for 3-6 months — then you're not financially ready yet.
That's not a reason to give up. It's a reason to work toward readiness deliberately. Sisters worth marrying will respect a man with a plan far more than a man rushing in unprepared.
