Also what if the wife didnt pardon this amount and they divorced soon after would he still have to pay the amount to her after the divorce?
Is it permissable for a brother to say that he would pay in Mahr somthing which is not in his means?
Praise be to Allaah.
nothing wrong with a wife letting her husband off paying the Mahr, because
Allaah says (interpretation of the meaning):
“but if they, of their own good pleasure, remit any part of it
to you, take it, and enjoy it without fear of any harm (as Allâh has made
it lawful)” [al-Nisaa’ 4:4]
deferred payment becomes due in the case of divorce after the consummation
of the marriage, even if the time-period involved is short – unless the
woman demands khul’ [a kind of divorce instigated by the wife] and gives
up her right to the money, as a compensation to the husband for leaving
him. This is OK is the khul’ is done for a legitimate reason and not
just for the sake of getting the money. Allaah says (interpretation of the
“… and you should not treat them with harshness, that you may take away part of the Mahr you have given them, unless they commit open illegal sexual intercourse…” [al-Nisaa’ 4:19]
It is permissible for the husband to say “I will give you such and such as a Mahr”, even if he does not own it; he should explain to them that this is to be paid later rather than sooner, and it will be a debt that he owes. And Allaah knows best.
