2:114Who is more unjust than him who forbids the remembrance of God’s name in places of worship, and contributes to their ruin? These ought not to enter them except in fear. For them is disgrace in this world, and for them is a terrible punishment in the Hereafter.

2:195And spend in the cause of God, and do not throw yourselves with your own hands into ruin, and be charitable. God loves the charitable.

2:251And they defeated them by God’s leave, and David killed Goliath, and God gave him sovereignty and wisdom, and taught him as He willed. Were it not for God restraining the people, some by means of others, the earth would have gone to ruin. But God is gracious towards mankind.
