It has been made lawful for you during the night of fasting to approach your women sexually. They are a garment for you and you are a garment for them. God knows that you used to betray yourselves so He has accepted your repentance, and forgiven you; now you may approach them and seek what God has written for you. You may eat and drink until the white thread is distinct from the black thread of dawn; then you shall complete the fast until night; and do not approach them while you are devoted in the temples. These are God's boundaries, so do not transgress them. It is thus that God makes His signs clear to the people that they may be righteous.

[2:183-187] Fasting, like timely prayers, the annual conference in Mecca and purification of blessings via sharing, originates from Abraham (22:73, 78). We are informed of any modification or correction in the ritual. For instance, verse 2:187 gives permission for sexual intercourse during the nights of Ramadan. Furthermore, the sectarian penalty of 60-day fasting for breaking the fast before sunset contradicts the Quran. The Quran makes no such distinction and considers breaking the fast before sunset to be equivalent to not fasting at all; it suggests a one-day-forone-day make up for the days missed.
[2:187] In the language of the Quran, the word layl (translated as night) is used to mark the period from sunset to sunrise.
