A marjaʿ al-taqlīd (“source of emulation”) is a senior Shia mujtahid whose juristic rulings a non-expert Shia Muslim follows. Choosing a marjaʿ. And therefore which set of rulings binds your worship. Is a personal religious decision, generally based on community guidance, family tradition, scholarly recommendation, and one’s own assessment of the marjaʿ’s learning.

Why marja matters in this app
Many fiqh rulings differ from one marja to the next. The 60-vs-50 lunar-year menopause threshold, the 2-vs-3 istihada categories, the Friday-prayer ruling, the cotton-test cadence, the right-then-left ghusl ordering. All of these are real divergences. A period tracker that does not know your marja can quietly tell you the wrong thing.
