Permitted for you (in the) nights (of) fasting (is) the approach to your wives. They (are) garments for you and you (are) garments for them. Knows Allah that you used to deceive yourselves, so He turned towards you and He forgave [on] you. So now have relations with them and seek what has ordained Allah for you. And eat and drink until becomes distinct to you the thread [the] white from the thread [the] black of [the] dawn. Then complete the fast till the night. And (do) not have relations with them while you (are) secluded in the masajid. These (are the) limits (set by) Allah, so (do) not approach them. Thus makes clear Allah His verses for [the] people so that they may (become) righteous.

But if you fear that not they both (can) keep (the) limits (of) Allah then (there is) no sin on both of them in what she ransoms concerning it. These (are the) limits (of) Allah, so (do) not transgress them. And whoever transgresses (the) limits (of) Allah then those - they (are) the wrongdoers.

He makes them clear to a people who know.

65:1
O Prophet! When you divorce [the] women, then divorce them for their waiting period, and keep count (of) the waiting period, and fear Allah, your Lord. (Do) not expel them from their houses, and not they should leave except that they commit an immorality clear. And these (are the) limits (of) Allah. And whoever transgresses (the) limits (of) Allah then certainly he has wronged himself. Not you know; Perhaps Allah will bring about, after that, a matter.
