2:178O you who believe! Retaliation for the murdered is ordained upon you: the free for the free, the slave for the slave, the female for the female. But if he is forgiven by his kin, then grant any reasonable demand, and pay with good will. This is a concession from your Lord, and a mercy. But whoever commits aggression after that, a painful torment awaits him.

2:187Permitted for you is intercourse with your wives on the night of the fast. They are a garment for you, and you are a garment for them. God knows that you used to betray yourselves, but He turned to you and pardoned you. So approach them now, and seek what God has ordained for you, and eat and drink until the white streak of dawn can be distinguished from the black streak. Then complete the fast until nightfall. But do not approach them while you are in retreat at the mosques. These are the limits of God, so do not come near them. God thus clarifies His revelations to the people, that they may attain piety.

2:216Fighting is ordained for you, even though you dislike it. But it may be that you dislike something while it is good for you, and it may be that you like something while it is bad for you. God knows, and you do not know.

2:246Have you not considered the notables of the Children of Israel after Moses? When they said to a prophet of theirs, “Appoint a king for us, and we will fight in the cause of God.” He said, “Is it possible that, if fighting was ordained for you, you would not fight?” They said, “Why would we not fight in the cause of God, when we were driven out of our homes, along with our children?” But when fighting was ordained for them, they turned away, except for a few of them. But God is aware of the wrongdoers.
