Firstly we would advise you to get acquainted with the background of Mutah and its Islamic legitimacy. There's no substitute for getting your head down and reading about it! So if you haven't yet read up on Mutah please go back to the previous page and start reading! Once you are convinced in your heart that Mutah is indeed a legitimate option in Islam and acceptable before the eyes of God, then move to the next level. . .
It is extremely important for you to now know the laws concerning Mutah. E.g. Are you and your potential spouse eligible to enter into a Mutah marriage contract? Are you aware of your mutual rights and responsibilities? Are you aware of your responsibilities in the event of pregnancy? Have you acquainted yourself with the possibilities of contraception? etc... To look into these matters further please go to the sections on Introduction To Mutah Marriage In Islam, and Mutah & Nikah Law.
Now that you are well aware of what Mutah entails, it is time to discuss this matter with whom you intend to enter the Mutah contract with. They too need to be comfortable with entering into the Mutah marriage with you. It might help you if you refer them to this site so like you they can also explore the topic.
Once you have mutually agreed that entering a Mutah contract is what you both want you need to discuss 1) The time period for which your Mutah marriage will last, 2) The Mahr 3) Any other conditions you may want to add.
1) You need to mutually agree in clear terms how long the initial Mutah contract will last. This needs to be clear and should not be obscure - because as soon as the time runs out you are no longer halal for each other unless you renew the Mutah and repeat this procedure again.
2) You need to mutually agree on a Mahr. Mahr is the gift that the man gives to his wife as part of the contract. It can be anything, and it is better if it is not extravagant in its value. Some hadith report that some of the Companions of the Prophet would enter into Mutah with a handful of dates or wheat as the Mahr.
3) You can agree to other conditions if you two so wish. It is not obligatory to do this, however, once you do agree to any conditions at this point it becomes obligatory for you to abide by them once you are in the Mutah marriage.
You are now ready to recite the Arabic formula of words, which, once completed, means that you two are now halal for each other in the eyes of God and the Law of Islam. Please note that this procedure can be done by the two persons wanting to enter the Mutah marriage themselves. There is no need for a Wakeel (someone who recites the seegha on your behalf) nor the need for witnesses. However you can opt for a Wakeel and you can also opt for witnesses if you so wish. If you like, you could even put this procedure into writing with both your signatures. These are options if you feel you would prefer it that way - however not necessary for your Mutah to be valid.
The seegha is quite short but must be recited in Arabic. Below you will find the Arabic formula written in English transliteration, along with its meaning. There is also a link to an audio file with the vows for the Mutah marriage recited in Arabic. It has been recited slowly with gaps, so you can repeat after it (if you want to). Otherwise you can just use the text below.
