O you who believe! When believing women come to you as emigrants examine them; Allah [swt] knows best as to their Faith, then if you ascertain that they are true believers send them not back to the disbelievers. They are not lawful for the disbelievers nor are the disbelievers lawful for them. But give them [disbelievers] that [amount of money] which they have spent [as their dowry] to them. And there will be no sin on you to marry them if you have paid their dowry to them. Likewise hold not the disbelieving women as wives and ask for that which you have spent [as dowry] and let them [disbelievers] ask back for that which they have spent. That is the judgement of Allah [swt], He judges between you. And Allah [swt] is All-Knowing, All-Wise.
He knows what is in the heavens and on earth and He knows what you conceal and what you reveal. And Allah [swt] is the All-Knower of what is in the breasts [of men].
No calamity befalls but by the Leave of Allah [swt] and whosoever believes in Allah [swt], He guides his heart. And Allah [swt] is the All-Knower of everything.
