They ask about the monthly course. Say, "It is a state of impurity; so keep apart from women during their monthly course and do not go near them until they are clean. When they have cleansed themselves, then you may go to them in the manner Allah has enjoined you." Most surely Allah loves those people who refrain from evil and keep themselves pure and 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's (Name) an excuse in your oaths against your doing good and acting piously, and making peace among mankind. And Allah is All-Hearer, All-Knower (i.e. do not swear much and if you have sworn against doing something good then give an expiation for the oath and do good). 224 God will not call you to account for that which is senseless in your oaths, but only for what is in your hearts; for God is forgiving and forbearing. 225 For those who swear that they will not approach their wives, there shall be a waiting period of four months: if they revert to conciliation, surely, God is most forgiving and ever merciful; 226 But if they are resolved on divorce - behold, God is all-hearing, all-knowing. 227 And divorced women shall wait (as regards their marriage) for three menstrual periods, and it is not lawful for them to conceal what Allah has created in their wombs, if they believe in Allah and the Last Day. And their husbands have the better right to take them back in that period, if they wish for reconciliation. And they (women) have rights (over their husbands as regards living expenses, etc.) similar (to those of their husbands) over them (as regards obedience and respect, etc.) to what is reasonable, but men have a degree (of responsibility) over them. And Allah is All-Mighty, All-Wise. 228
