4:29O you who believe! Do not consume each other’s wealth illicitly, but trade by mutual consent. And do not kill yourselves, for God is Merciful towards you.

4:66Had We decreed for them: “Kill yourselves,” or “Leave your homes,” they would not have done it, except for a few of them. But had they done what they were instructed to do, it would have been better for them, and a firmer confirmation.

4:94O you who believe! When you journey in the way of God, investigate, and do not say to him who offers you peace, “You are not a believer,” aspiring for the goods of this world. With God are abundant riches. You yourselves were like this before, and God bestowed favor on you; so investigate. God is well aware of what you do.

4:135O you who believe! Stand firmly for justice, as witnesses to God, even if against yourselves, or your parents, or your relatives. Whether one is rich or poor, God takes care of both. So do not follow your desires, lest you swerve. If you deviate, or turn away—then God is Aware of what you do.
