The core nikah requirements are: two spouses who are free to marry each other, the free consent of both, a clear offer and acceptance (ijab and qabul), the presence of the bride’s wali (guardian), two witnesses, and a mahr (marriage gift) given to the bride. Most scholars treat the wali and witnesses as essential to validity, while the Hanafi and Maliki schools differ on some details, which is why couples are always advised to finalize the contract with a qualified imam or scholar. Learning these basics before the big day is one of the best ways to prepare for marriage the Islamic way.
This guide explains each requirement in plain language, shows where the schools of thought agree and differ, and lists what makes a nikah invalid.
Key takeaways
- A nikah needs consent, offer and acceptance, a wali, two witnesses and a mahr, according to the majority of scholars.
- A woman cannot be married without her consent; a forced marriage can be annulled.
- The mahr is the bride’s right; if it is not named, she is still owed a fair mahr.
- An imam, a sermon and a walimah are Sunnah or customary, but civil registration is often legally essential.
Pillars, Conditions and Sunnah: What Is the Difference?
Fiqh books divide the requirements of nikah into categories, and knowing them prevents a lot of confusion:
- Pillars (arkan): the parts that make up the contract itself. Without them, there is no marriage.
- Conditions of validity (shurut): requirements that must be met for the contract to count, such as the spouses being free to marry.
- Sunnah and recommended acts: blessed practices such as the marriage sermon and the wedding meal. Leaving them does not invalidate the nikah.
Scholars do not always place each item in the same category. The Shafi’i school, for example, counts the wali and witnesses among the pillars, while others list them as conditions. In practice, the result is similar: the majority hold that a nikah without them is not valid.
The Essential Requirements of a Valid Nikah
1. Two spouses who are free to marry
The bride and groom must not be related in a way that makes marriage forbidden, such as by blood, breastfeeding or marriage, as listed in Surah an-Nisa 4:23. The bride must not be married to someone else or still in her waiting period (‘iddah) after divorce or the death of a husband. A man may not have more than four wives at once.
Religion also matters. A Muslim woman may marry only a Muslim man (2:221, 60:10), while a Muslim man may marry a Muslim woman or a chaste woman of the People of the Book (5:5). Our guide to mahram and non-mahram in Islamic teachings explains the family relationships that rule out marriage.
2. Consent of both spouses
Marriage in Islam is a contract, and a contract requires agreement. The Prophet ﷺ said that a previously married woman is not to be married until she is consulted, and a woman who has never married is not to be married until her permission is sought; when asked how she gives it, he said, by remaining silent (Sahih al-Bukhari and Sahih Muslim). When Khansa’ bint Khidam was married by her father against her wishes, the Prophet ﷺ annulled the marriage (Sahih al-Bukhari).
3. The wali (guardian)
The wali is usually the bride’s father, then her paternal grandfather, brother or other close male relatives in a set order. The Prophet ﷺ said, “There is no marriage except with a wali” (narrated by Abu Dawud and at-Tirmidhi). The Maliki, Shafi’i and Hanbali schools treat the wali as required. The Hanafi school allows an adult, sane woman to contract her own marriage, while giving the wali a right to object if the match is clearly unsuitable. Where a woman has no Muslim wali, a Muslim judge or recognized authority can act in that role.
4. Two witnesses
The marriage must be witnessed, so that it is public and not secret. Most scholars require two adult, sane Muslim men; the Hanafi school also accepts one man and two women. The Shafi’i and Hanbali schools add that witnesses should be upright in character. The Maliki school emphasizes announcing the marriage and requires the witnessing to take place before the couple live together.
5. Offer and acceptance (ijab and qabul)
One side offers (“I marry you to my daughter… for the agreed mahr”) and the other accepts (“I accept”). The offer and acceptance must be clear, in the same sitting, and match each other. The marriage must also be intended as permanent: a contract with a fixed end date is invalid according to Sunni scholars. Either side may appoint a representative (wakil) to speak for them.
6. The mahr
Allah commands giving women their mahr as a gift given willingly (Surah an-Nisa 4:4). It belongs to the bride, not her family. It can be money, gold or anything of value agreed upon; the Prophet ﷺ once told a poor man to look for something “even an iron ring” (Sahih al-Bukhari). Most scholars hold the nikah is still valid if the mahr is not named, but the wife is then owed a mahr similar to that of women like her.

What Is Sunnah but Not Required
Several practices bring blessing to the nikah without being conditions of it:
- The marriage sermon (khutbat al-hajah), which the Prophet ﷺ taught to open important matters.
- Announcing the marriage rather than keeping it quiet.
- The walimah: the Prophet ﷺ told ‘Abd al-Rahman ibn ‘Awf, “Give a wedding feast, even if only with one sheep” (Sahih al-Bukhari and Sahih Muslim).
- Congratulating the couple with the Prophetic dua: Barak Allahu laka, wa baraka ‘alaykuma, wa jama’a baynakuma fi khayr, “May Allah bless you, shower His blessings upon you both, and bring you together in goodness” (narrated by Abu Dawud and at-Tirmidhi).
An imam is not technically required to perform a nikah, but having a knowledgeable person officiate helps ensure every condition is met.
What Makes a Nikah Invalid
A nikah is invalid, or may be annulled, in cases such as:
- Marrying someone the Quran forbids, including a woman still in her ‘iddah.
- A marriage forced on a woman without her consent.
- A temporary marriage with a fixed end date.
- A secret marriage with no witnesses (and, for the majority, no wali).
- Shighar, where two men marry each other’s daughters or sisters with no mahr, which the Prophet ﷺ prohibited (Sahih al-Bukhari and Sahih Muslim).
- A contract made while either spouse is in ihram, according to the majority, based on a hadith in Sahih Muslim.
Register your marriage. In many countries, a religious nikah alone is not legally recognized. Civil registration protects both spouses’ rights in matters such as inheritance, residence and custody. Ask your imam whether he can register the marriage or whether you need a separate civil ceremony.
After the Contract
A valid contract is only the beginning. The Quran describes spouses as garments for one another (2:187), and a strong marriage depends on understanding the rights of husband and wife in Islam. If you are still at the stage of getting to know a potential spouse, our list of questions to ask before marriage in Islam will help you cover the essentials. One-to-one lessons in our Islamic marriage course cover these rights and responsibilities in depth.
Frequently Asked Questions
Can a woman be her own wali?
According to the Maliki, Shafi’i and Hanbali schools, no: a wali is required for the nikah to be valid. The Hanafi school allows an adult, sane woman to contract her own marriage, though involving her family is still strongly encouraged. Ask a qualified scholar which view applies to your situation.
Is mahr required for a valid nikah?
Mahr is obligatory, but most scholars do not count it as a pillar. If it is left unnamed, the marriage is still valid and the wife is owed a fair mahr in line with women of similar standing. It is best to agree on it clearly before the contract.
Can a nikah be done over the phone or video call?
Contemporary scholars differ. Many advise against conducting the offer and acceptance remotely and recommend appointing a representative (wakil) who attends in person with the witnesses. Consult a local scholar or Islamic center before arranging a remote nikah.
Do we need an imam to perform the nikah?
No, an imam is not a condition of validity; the requirements are the ones listed above. However, an experienced officiant makes sure nothing is missed and can often help with legal registration.
What should we learn before the nikah?
Learn the requirements of the contract, the rights and duties of each spouse, and how to handle disagreements in a healthy, Islamic way. Our marriage preparation classes cover these topics with qualified teachers before the big day.
