In Islam, a valid Nikkah (marriage) requires certain conditions. Here are the key ones:

*Conditions for a Valid Nikkah*

1. *Mutual Consent*: Both the bride and groom must give their free and willing consent to the marriage.

2. *Mahr (Dowry)*: The groom must pay the bride a mandatory gift, known as Mahr, which is a symbol of his commitment.

3. *Witnesses*: Two male witnesses (or one male and two female witnesses) must be present to attest to the marriage.

4. *Proposal and Acceptance*: The groom must propose to the bride, and she must accept his proposal in the presence of witnesses.

5. *Capacity and Eligibility*: Both parties must be:

– Muslim (unless the groom is a Kitabi, i.e., from the People of the Book, and the bride is a Muslim)

– Of sound mind and mature enough to give consent (typically 18 years old)

– Free from any impediments, such as being already married or closely related

6. *Public Declaration*: The Nikkah must be publicly declared to ensure transparency and avoid secret marriages.

*Additional Requirements*

1. *Wali (Guardian)*: A Muslim woman’s Wali (guardian) must be present to ensure her well-being and interests are protected.

2. *Khutbah (Sermon)*: A Khutbah, a sermon emphasizing the importance of marriage and responsibilities, is often recited before the Nikkah.

*Invalidating Factors*

1. *Coercion or Force*: If either party is coerced or forced into the marriage, it is invalid.

2. *Lack of Witnesses*: Without the required witnesses, the Nikkah is not valid.

3. *Ineligibility*: Marriage to someone who is ineligible (e.g., a close relative or someone already married) invalidates the Nikkah.

It’s essential to note that these conditions may vary slightly depending on the specific Islamic school of thought or local customs.
