Bulūgh is the threshold at which a person becomes religiously responsible. Worship obligations. Daily prayer, fasting, Hajj, financial obligations like zakat and khums. Apply from this age onward.
For girls (Shia Jaʿfari)
- A. Sistani / Khomeini / A. Khamenei: 9 lunar years completed (A. Sistani Ruling 434, Khomeini Tahrir al-Wasilah Vol I l. 1794).
- A. Makarem Shirazi: 10 lunar years for menarche specifically (ISSUE 195). Makarem distinguishes menarche (age 10) from ʿiddah-exemption age (age 9). The only marja to do so among the three Tuhr supports.
Implication for hayd tracking
Bleeding before bulūgh is not classified as hayd. The Tuhr app’s onboarding takes date of birth precisely so it can apply the correct marja’s menarche gate before classifying any pre-bulūgh bleeding.

For A. Makarem Shirazi, the menarche threshold is 10 lunar years (distinct from his ʿiddah-exemption age of 9 in ISSUE 871). Among Tuhr's three supported marjas, A. Makarem is alone in using 10 for menarche.
