They ask you about menstruation. Say, "It is an impurity, so keep away from women during it and do not approach them until they are cleansed; when they are cleansed you may approach them as God has ordained. God loves those who turn to Him in penitence and He loves those who keep themselves clean. 222 Your wives are a tilth for you, so go to your tilth when or how you will, and send (good deeds, or ask Allah to bestow upon you pious offspring) before you for your ownselves. And fear Allah, and know that you are to meet Him (in the Hereafter), and give good tidings to the believers (O Muhammad SAW). 223 And make not Allah because of your swearing (by Him) an obstacle to your doing good and guarding (against evil) and making peace between men, and Allah is Hearing, Knowing. 224 Allah does not take you to task for oaths which are made unintentionally but He does take you to task for deeds which your hearts have done; and Allah is Oft Forgiving, Most Forbearing. 225 Those who take an oath that they will not approach their wives shall have four months of grace; and if they go back [on their oath] - behold, God is much-forgiving, a dispenser of grace. 226 If they choose divorce, God is All-hearing and All-knowing. 227 And the divorced women shall undergo, without remarrying, a waiting-period of three monthly courses: for it is not lawful for them to conceal what God may have created in their wombs, if they believe in God and the Last Day. And during this period their husbands are fully entitled to take them back, if they desire reconciliation; but, in accordance with justice, the rights of the wives [with regard to their husbands] are equal to the [husbands'] rights with regard to them, although men have precedence over them [in this respect]. And God is almighty, wise. 228
