Laa yastaazinukal lazeena yu'minoona billaahi wal Yawmil Aakhiri ai yujaa hidoo bi amwaalihim wa anfusihim; wallaahu 'aleemum bilmut taqeen
Those who believe in Allah and the Last Day will never ask your leave to be excused from striving (in the cause of Allah) with their belongings and their lives. Allah fully knows the God-fearing.
