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.

4:162But those among them firmly rooted in knowledge, and the believers, believe in what was revealed to you, and in what was revealed before you; and the observers of prayers, and the givers of charity, and the believers in God and the Last Day—upon these We will bestow an immense reward.
