(Though during Fasting you must abstain from all the urges of nature including the sexual urge) it is made lawful for you on the nights of the fasts to approach and lie with your wives (for sexual relationship). They are (a sort of) garment for you and you are (a sort of) garment for them. Allâh knows that you have been doing injustice to yourselves (by restricting conjugal relations with your wives even at night), so He turned to you with mercy and provided you relief; now enjoy their company (at night during Ramadzân) and seek what Allâh has ordained for you. Eat and drink till the white streak of the dawn becomes distinct to you from the black streak (of the darkness), then complete the fast till nightfall. And you shall not lie with them (- your wives) while you perform I`tikâf (- while you are secluding in the mosque for prayer and devotion to God). These are the limits (imposed) by Allâh so do not approach these (limits). Thus does Allâh explains His commandments for people that they may become secure against evil. - Quran 2:187
