[2:234]

Such of you as die and leave behind them wives, they (the wives) shall wait, keeping themselves apart, four months and ten days. And when they reach the term (prescribed for them) then there is no sin for you in aught that they may do with themselves in decency. Allah is informed of what ye do.

[2:235]

There is no sin for you in that which ye proclaim or hide in your minds concerning your troth with women. Allah knoweth that ye will remember them. But plight not your troth with women except by uttering a recognised form of words. And do not consummate the marriage until (the term) prescribed is run. Know that Allah knoweth what is in your minds, so beware of Him; and know that Allah is Forgiving, Clement.

[2:236]

It is no sin for you if ye divorce women while yet ye have not touched them, nor appointed unto them a portion. Provide for them, the rich according to his means, and the straitened according to his means, a fair provision. (This is) a bounden duty for those who do good.

[2:237]

If ye divorce them before ye have touched them and ye have appointed unto them a portion, then (pay the) half of that which ye appointed, unless they (the women) agree to forgo it, or he agreeth to forgo it in whose hand is the marriage tie. To forgo is nearer to piety. And forget not kindness among yourselves. Allah is Seer of what ye do.
