“strive”
in Edition Clear Qur'an by Talal Itani / Al-Maaida (The Table)
5:33The punishment for those who fight God and His Messenger, and strive to spread corruption on earth, is that they be killed, or crucified, or have their hands and feet cut off on opposite sides, or be banished from the land. That is to disgrace them in this life; and in the Hereafter they will have a terrible punishment.
5:35O you who believe! Be conscious of God, and seek the means of approach to Him, and strive in His cause, so that you may succeed.
5:54O you who believe! Whoever of you goes back on his religion—God will bring a people whom He loves and who love Him, kind towards the believers, stern with the disbelievers. They strive in the way of God, and do not fear the blame of the critic. That is the grace of God; He bestows it upon whomever He wills. God is Embracing and Knowing.
5:64The Jews say, “God’s hand is tied.” It is their hands that are tied, and they are cursed for what they say. In fact, His hands are outstretched; He gives as He wills. Certainly, what was revealed to your from your Lord will increase many of them in defiance and blasphemy. And We placed between them enmity and hatred, until the Day of Resurrection. Whenever they kindle the fire of war, God extinguishes it. And they strive to spread corruption on earth. God does not love the corrupters.
