The role of witnesses at a nikah: who can it be and how many?
Who can be a witness at a nikah and how many do you need? An explanation of the requirements, the numbers, and why witnesses matter so much.

Witnesses are part of a valid nikah, but what exactly are the requirements? How many do you need, who can be a witness, and why is it actually obligatory? On this page we go through it practically, so you know who you can ask and what to watch for. It's an explanation of the general rules; on some details the schools of law differ, so for your situation an imam or scholar is the right person to ask. If you first want the complete picture of the requirements, read the conditions for a valid nikah.
How many witnesses do you need?
The standard requirement is two witnesses. That goes back to the well-known narration that there is no marriage without a wali and two upright witnesses. Most scholars agree that a nikah without witnesses is not valid.
So two is the starting point. It's not the case that more witnesses are "better" or required; two is enough, provided they meet the conditions. Those conditions are the next point.
Who can be a witness?
A few conditions apply to the witnesses that recur in most sources:
The witnesses are Muslim. A non-Muslim witness doesn't count toward the validity of the nikah. Note: a Dutch registrar at the civil marriage isn't therefore automatically a valid witness for the nikah.
The witnesses are adult and of sound mind. Children can't fulfil this role.
The witnesses are upright, that is, trustworthy and of good conduct. In practice it comes down to them being people you can take at their word, so that their testimony has value.
Can women be witnesses?
Here the schools of law differ, and it's good to name that honestly. According to some schools, a valid testimony consists of two men, or otherwise one man and two women. Under that view, the presence of at least one male witness is required.
Other scholars and schools look at this differently. Because the precise rule differs by school of law, this is typically a question to put to an imam or scholar who knows your situation and school of law. This article gives you the background so you go into that conversation well prepared, not a ready-made ruling.
Why are witnesses obligatory anyway?
The requirement of witnesses isn't a formality; there's a clear idea behind it. The main purpose is that the marriage becomes known and doesn't take place in secret. Islam holds that a marriage should be open and recognisable, precisely to prevent mistrust and suspicion.
In addition, witnesses protect the rights that arise from the marriage. Should doubt or dispute arise later about the existence of the marriage, there are people who can confirm that it was concluded. This protects, among other things, the position of the woman and the lineage of any children.
Witnesses thus belong to the same idea as the wali and the making known of the marriage: a nikah is an open, serious union, not a secret arrangement. Read more about that protective role of the wali in what a wali is.
Witnesses and the civil marriage in the Netherlands
In the Netherlands it's useful to know that the witnesses at the nikah are something other than the witnesses at the civil marriage. At the municipality you can have witnesses for the civil part, but they don't automatically fulfil the religious role. For the nikah, the Islamic conditions we described above apply.
In practice, many couples arrange both on the same day: first the civil marriage, then the nikah with their own Islamic witnesses present. Why that order is what it is and what a nikah does and doesn't mean legally, you can read in is an Islamic marriage legally valid in the Netherlands and in what a nikah is.
