The phrase fi sabilillah (فِي سَبِيلِ ٱللَّٰهِ, fī sabīli llāhi) is an Arabic expression meaning "in the cause of Allah", or more befittingly, "for the sake of Allah". It is a general term, and it should be applied in all those situations where there is a need to serve Islam and Muslims. Those scholars consider using the Zakah money to finance the Da’wah, education, and public welfare programs permissible. They say that the expression ‘for the poor and needy’ can also mean ‘for the benefit of the poor and needy.’ The modern jurists also argue that in the past Muslim governments used to build Mosques and schools and used to finance public welfare projects.
