Quran Chapter 2 Verse 237-240
And if you divorce them before you have touched them and you have already specified for them an obligation, then [give] half of what you specified – unless they forego the right or the one in whose hand is the marriage contract foregoes it. And to forego it is nearer to righteousness. And do not forget graciousness between you. Indeed Allah , of whatever you do, is Seeing.
Maintain with care the [obligatory] prayers and [in particular] the middle prayer and stand before Allah , devoutly obedient.
And if you fear [an enemy, then pray] on foot or riding. But when you are secure, then remember Allah [in prayer], as He has taught you that which you did not [previously] know.
And those who are taken in death among you and leave wives behind – for their wives is a bequest: maintenance for one year without turning [them] out. But if they leave [of their own accord], then there is no blame upon you for what they do with themselves in an acceptable way. And Allah is Exalted in Might and Wise.
