Prohibition from befriending unbelievers and clarifying their reality

O YOU WHO BELIEVE, do not take My enemies and your enemies as friends. You show kindness to them, but they reject the true way that has come to you. They expelled the Prophet and you, for you believe in God your Lord. If you have come out to struggle in My cause having sought My acceptance, (do not be) friendly with them in secret. I know what you hide and what you disclose. Whoever of you does this will have gone astray from the right path.

If they gain ascendancy over you, they will become your enemies, and employ their hands and tongues with evil designs, and wish that you also became disbelievers.

Neither your blood relations nor your children will be of any avail to you on the Day of Resurrection. He will judge between you, for God sees what you do.
