When Your Partner Wants to Become Muslim Before You Marry: A Guide for Both of You

I am Ben. I built Revertly, and I am a revert myself. I am also married to an Indonesian woman. So the situation in this article is not something I read about. I lived it from the inside: the questions from family on both sides, the paperwork, and the first clumsy prayers.

If you are a Muslim woman with a non-Muslim partner, or the partner who is thinking about Islam, this is for both of you. It covers what actually has to happen, how it works in Indonesia, what he should learn first, and how to get through it without pressure ruining something good.

First, the honest part: it has to be his choice

The Quran says it plainly: “There is no compulsion in religion” (Quran 2:256). Nobody can be made Muslim. A shahada said only to get through a wedding, with nothing behind it, helps no one, least of all the marriage.

That does not mean love is a bad reason to start. Many reverts first opened a book about Islam because of a person. Learning about Islam because you love someone is normal and good. The goal is that somewhere along the way, it becomes his. He prays because he wants to stand before Allah, not because she is watching.

Pressure works against this. If he feels pushed, he may say the words and then quietly resent them. If he feels free, he can actually look at Islam with open eyes. That is the version that lasts.

Why it matters for the marriage

In mainstream Islamic law, a Muslim woman marries a Muslim man. This comes from the Quran (2:221 and 60:10) and is the position of all four Sunni schools. A Muslim man may marry a Christian or Jewish woman, with conditions, but the same is not allowed the other way round. In Indonesia, the MUI (the Indonesian Ulema Council) goes further and holds that interfaith marriage is not valid in either direction.

For her, this is not a cultural detail or her parents being strict. If she cares about her faith, she cannot have a valid nikah with a man who is not Muslim. Knowing this early saves a lot of hurt. He is not being tested or rejected. The rule is simply part of what she believes.

How it works in Indonesia

Indonesia's Marriage Law (No. 1 of 1974) says a marriage is valid when it is performed according to the religion of the couple. In practice, that means a couple of two different religions generally cannot register their marriage. For years some district courts still approved interfaith registrations. In July 2023 the Supreme Court issued a circular, SEMA No. 2 of 2023, telling judges not to grant those requests.

So for a Muslim woman and a foreign (“bule”) boyfriend, the usual path looks like this:

1. He says the shahada, usually at a mosque in front of an imam and two witnesses.
2. He gets a conversion certificate (often called a sertifikat mualaf or surat keterangan mualaf). Many larger mosques issue these, and some go through the local MUI or KUA.
3. They register the marriage at the KUA, the Office of Religious Affairs, which handles marriages between Muslims. He will need his passport and the conversion certificate, and foreigners are usually asked for papers from their own embassy too.
4. The akad nikah follows in the normal way, with her wali and the witnesses.

Procedures, document lists and timelines differ from region to region and change over time. Go to the KUA in her district early and ask for the current list. If you marry outside Indonesia, ask the local mosque and the Indonesian embassy there what they need.

The shahada itself

It is short. It takes less than a minute, and he can learn the words in an evening.

أَشْهَدُ أَنْ لَا إِلَٰهَ إِلَّا اللَّهُ، وَأَشْهَدُ أَنَّ مُحَمَّدًا رَسُولُ اللَّهِ

Ash-hadu an la ilaha illallah, wa ash-hadu anna Muhammadan rasulullah.

“I bear witness that there is no god but Allah, and I bear witness that Muhammad is the Messenger of Allah.”

Before Allah, witnesses are not a condition. A sincere shahada said alone in a quiet room counts. Witnesses matter for the certificate and the marriage paperwork, which is why most men in this situation say it at a mosque. Our guide How to Convert to Islam goes through the meaning in more detail.

A tip from experience: let him meet the imam before the day. A short coffee and a chance to ask questions turns a nervous ceremony into something he will remember well.

After the shahada: what he really needs first

New Muslims often get handed a list of fifty things. Most of it can wait. The first month is about one thing: the prayer.

Learn now

• Ghusl. A full ritual shower after becoming Muslim. The Hanbali school treats it as required, the other schools as recommended in most cases. In practice, do it. Here is how to do ghusl after shahada.
• Wudu. The washing before prayer. It takes a few minutes to learn. See how to make wudu.
• The five daily prayers. Start with the two-rakat Fajr and build up. See how to pray.
• Al-Fatiha. It is recited in every rakat. While he is still memorizing it, there is an allowance for beginners: read how to pray before you know Al-Fatiha.

Can wait

• Long surahs, extra sunnah prayers, and Arabic grammar
• Debates between schools and online arguments
• Changing his wardrobe, his name, or his whole social life overnight

A realistic first month

• Week 1: ghusl, wudu, and Fajr. Pray what he can, with the text in front of him if needed.
• Week 2: add Maghrib, then the other prayers. Start Al-Fatiha, one verse a day.
• Week 3: all five prayers most days. Al-Fatiha mostly by heart. First Friday prayer at the mosque, ideally with someone he knows.
• Week 4: a short surah for the second rakat, and the Tashahhud. Missed prayers happen. He makes them up and keeps going.

If you want to send him something: Revertly teaches the prayer from zero, step by step, in English and 11 other languages. An animated figure shows each position while the Arabic is recited, and wudu is taught the same way. It is on the App Store. I built it partly because I needed it myself.

For her: how to support him without pressure

• Learn together. Pray next to him, or let him lead a prayer once he is ready. Read a short tafsir together. Many born Muslims find they relearn things they took for granted.
• Be patient with mistakes. He will mispronounce words, forget a rakat, and pray facing slightly the wrong way. That is how everyone learns. Correct gently, and not every time.
• Do not police him. Asking “did you pray Asr?” five times a day turns worship into a checklist for you. Let his prayer be between him and Allah.
• Find him people. A kind imam, an ustadz who speaks English, or a group of other reverts. He needs friends who were where he is, not only your family.
• Handle your family. Some relatives will ask if he is “really” Muslim or test him in public. Protect him from that. His faith is not theirs to judge.
• Respect his family. His parents may be scared or hurt. Do not compete with them. Help him stay close to them.

For him: the honest feelings

If you are the one becoming Muslim, it is normal to feel more than one thing at once. You might feel drawn to Islam and also afraid of losing yourself in it.

• Identity. You do not stop being from your country, liking your music, or being yourself. Islam asks you to drop what is forbidden, not your whole personality.
• Family back home. Telling your parents can be the hardest part. Our guide on telling your family you became Muslim has practical wording, and praying when your family is not Muslim covers daily life around them.
• Your name. You do not have to change it.
• Real changes. No alcohol and no pork. Food needs to be halal. And the relationship itself changes: Islam does not allow physical intimacy before marriage. For a couple who have been together for a while, that can be a real adjustment. Talk about it openly, as two adults, and give each other grace.
• Doubts. Having questions does not mean you are failing. Ask them. A good imam will be glad you asked.

The Prophet (peace be upon him) taught that Islam wipes away what came before it. You start with a clean page. What you write on it is between you and Allah.

One last thing

When I look back, the wedding was one day. The prayer is every day. If both of you keep that in mind, the paperwork becomes the easy part, and the faith has room to grow on its own. After the shahada, our checklist on what to do after taking shahada is a good next read.
