(Fatwa: 1297/1297/M=11/1434)
It is unlawful to offer money for leading tarawih and for Hafiz it is unlawful to demand it. No doubt salah shall be valid behind a person who takes money for leading tarawih salah but it shall be makrooh. Both the persons i.e. one who gives money and one who takes it shall be sinful. If money is not paid then the person who does not give it shall not be sinful. However, if there is none who could lead tarawih salah without money, in this case tarawih should be offered reciting Surah al-Feel. The salary of imamah is lawful for the person who leads five times salah. However, it is not correct for permanent imam to take compensation for tarawih salah.
Allah knows Best!
