(20:75-76) He who comes to Him being faithful (Arab. مُؤْمِنًا, mu'minan), doing good works, for those will be the highest ranks. Gardens of Eden with rivers flowing beneath them, abiding therein. Such is the reward of he who is developed.
(9:72) God has promised the faithful (Arab. الْمُؤْمِنِينَ, l-mu'minīna) men and women gardens with rivers flowing beneath it, in which they will abide, and pleasing homes in the gardens of Eden. The acceptance from God is the most important; such is the greatest success.
Encouraging those who acknowledge
(4:84) So fight in the path of God. You are not responsible except for yourself. Enjoin those who acknowledge (Arab. الْمُؤْمِنِينَ, l-mu'minīna), "Perhaps God will put a stop to the might of those who deny." God is far Stronger (in) might, and far Stronger (in) punishment.
(49:14) The Arabs said, "We acknowledge." Say, "You have not acknowledged; but you should say, "We have peacefully surrendered", for acknowledgement has not yet entered into your hearts." If you obey God and His messenger, He will not put any of your works to waste. God is Forgiver, Compassionate.
