A text in English: And it is not lawful for you to take back anything out of what you have given them. There is, however, an exception to this; if you fear that they might not be able to keep within the limits imposed by Allah, there is no harm if both agree mutually that the wife should obtain divorce by giving something as compensation to the husband.
What's the text in Czech? Není vám dovoleno vzít nic z toho, co jste jí dali, leda že oba se obáváte, že nedodržíte omezení Bohem daná. Jestliže se obáváte, že nedodržíte omezení Bohem daná, tedy nebude pro žádného z obou vás hříchem, jestliže žena se vykoupí.
