2:143Thus We made you a moderate community, that you may be witnesses to humanity, and that the Messenger may be a witness to you. We only established the direction of prayer, which you once followed, that We may distinguish those who follow the Messenger from those who turn on their heels. It is indeed difficult, except for those whom God has guided. But God would never let your faith go to waste. God is Kind towards the people, Merciful.

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.
