(3) Nay, but they will deny their worship of them, and become opponents unto them.

(4) These twain (the believers and the disbelievers) are two opponents who contend concerning their Lord. But as for those who disbelieve, garments of fire will be cut out for them; boiling fluid will be poured down on their heads,

(5) Even so have We appointed unto every prophet an opponent from among the guilty; but Allah sufficeth for a Guide and Helper.

(6) Hath not man seen that We have created him from a drop of seed? Yet lo! he is an open opponent.
