A bio-data does two jobs at once: it introduces you to another family, and it hands your details to people you do not yet know. So an Islamic bio-data follows two principles side by side — share what must be shared, truthfully, and keep safe what does not need to be shared yet.
We covered the general structure and samples in Marriage bio-data format. This is the next step: what you must write, what you should not, and what to share later.
The principle: honesty
The Messenger of Allah ﷺ said: “Whoever cheats is not one of us.” (Sahih Muslim, Book of Faith). In a decision as large as marriage this applies all the more. Lowering your age, adding to your height, inflating income or education — small as they seem, they build the start of a marriage on something untrue.
Honesty does not mean putting everything on the first page. It means that what you write is true, and that nothing which could affect the decision is hidden.
What you must write
1. Correct age, height and marital status
The first filtering happens on these three. If there was a previous marriage, or there are children, say so clearly — if the other family learns it later they will see it as concealment, and knowing it is their right.
2. Religious life — as it is
Some think writing more in the religious section brings better proposals. But a family genuinely looking for a practising spouse sees the reality as soon as you talk. Write humbly and truthfully:
“I try to pray all five prayers regularly; Fajr is sometimes late, and I am working on it.”
A line like that builds far more trust than “fully practising”.
3. Work and source of income
State your profession and source of income clearly. The exact income does not have to be in the first bio-data, but whatever you write must be real. If the family asks, answer honestly.
4. Significant health matters
A long-term illness, or any health matter that could affect married life, should not be hidden. The first bio-data need not give details — “there is a health matter; I will share details as we move forward” is enough. But the other side must know before a decision is made.
5. Guardian’s name and contact
The name, relationship and number of a father, brother or other mahram guardian. This is the respectful way for a marriage conversation to begin, and for a bride it is also protection.
What not to write
| Detail | Why not |
|---|---|
| The bride’s own mobile number | A bio-data passes through many hands; it opens the door to direct calls and messages from strangers |
| Full home address | District and upazila are enough; the home address comes after trust |
| National ID number or photo | Risk of identity fraud; it is not needed before marriage |
| Exact office address and desk | Someone could go to your workplace to “check” — without your permission |
| Remarks about other families or past proposals | It slides into backbiting, and reflects badly on you too |
| A detailed list of assets | Marriage is about the person, not property — and it attracts the wrong interest |
Deciding about photos
Avoid attaching a bride’s photo to the bio-data. Once a photo is in someone’s hands you cannot know where it goes, and you cannot take it back. When a conversation genuinely moves forward, showing it separately to that one family is safer.
With an online profile this control is easier. On Halal Nikah, for example, photos can be kept private; anyone who wants to see them sends a request, and you allow it for 3, 7, 15 or 30 days — when it runs out, the photos close again.
What to share later
Some things are not untrue, but they are not for the first page either. Share them as things move forward, with guardians present:
- The exact income
- Family complications or responsibilities (such as caring for ill parents)
- Details of health matters
- Expectations such as where you will live after marriage, or whether the wife will keep working
This is not concealment — it is telling the right people at the right time.
