2:21O people! Worship your Lord who created you and those before you, that you may attain piety.

2:63And recall when We received a pledge from you, and raised the Mount above you: “Take what We have given you earnestly, and remember what is in it, that you may attain righteousness.”

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.
