Key points
- A girl becomes baligh with her first period, a wet dream (ihtilam) or pregnancy.
- None of these count before the age of nine lunar years.
- If no sign appears, she is baligh on completing fifteen lunar years.
Why bulugh matters
Bulugh (بلوغ), puberty, is the moment a child becomes accountable. From then on prayer, fasting, hijab and every other obligation are binding, and her deeds are recorded. Knowing the exact signs helps parents prepare their daughters and avoid missed fasts or prayers.
The signs in the Hanafi school
For a girl, bulugh is established by any of these:
- her first menstruation (haiz);
- a wet dream with discharge (ihtilam);
- pregnancy.
Other bodily changes, such as breast development or pubic hair, are not by themselves treated as signs of bulugh in the Hanafi school, although other schools consider some of them.
The ages: nine and fifteen
A girl cannot be baligh before nine lunar years: blood seen before then is not haiz. If none of the signs have appeared, she is considered baligh when she completes fifteen lunar years. This is the position on which the Hanafi fatwa is given. A lunar year is about 354 days, so fifteen lunar years is around fourteen and a half solar years.
What begins at bulugh
- The five daily prayers and Ramadan fasts.
- Hijab and the rules of modesty with non-mahram men.
- The rulings of haiz: knowing when to stop and resume prayer, and making ghusl.
- Making up fasts missed during haiz in Ramadan.
Prayers she misses after bulugh must be made up, so parents should make sure she knows the signs.
Preparing her beforehand
The Prophet ﷺ told parents to teach children to pray at seven and to be firmer at ten (Abu Dawud). Preparing early means obligations arrive as a habit, not a shock. See preparing your daughter for puberty, and use the Puberty Calculator to find her fifteen-lunar-year date.
