“strive”
in Edition Clear Qur'an by Talal Itani / Al-Hajj (The Pilgrimage)
22:51But those who strive against Our revelations—these are the inmates of Hell.
22:78And strive for God, with the striving due to Him. He has chosen you, and has not burdened you in religion—the faith of your father Abraham. It is he who named you Muslims before, and in this. So that the Messenger may be a witness over you, and you may be witnesses over the people. So pray regularly, and give regular charity, and cleave to God. He is your Protector. What an excellent Protector, and what an excellent Helper.

Those who spend their wealth by night and day, privately and publicly, will receive their reward from their Lord. They have nothing to fear, nor shall they grieve.
