❓ Frequently asked questions
Must every Muslim pay 20% of income?
No. Qur’an 8:41 addresses war gains; the annual-surplus extension is Ja’fari law, not universal.
How is khums split?
In Ja’fari law, half Sahm-e-Imam and half Sahm-e-Sadat — follow your marja’ for distribution.
Sunni view?
No annual income khums; surplus wealth falls under zakat instead.
