Re: Mehr. Serious question.
Arghhhhhhhhhh .. stop cutting and pasting folks .. let me asnwer in 3 points
Meher is divided in 2 parts, Mu'ajjal and Mowajjal. Both should be announced on Nikah form.
Mu'ajjal needs to be given ASAP, but wife can forgive it. Mowajjal needs to be given in case of divorce and is mandatory (only if divorce happens).
Amount of Mowajjal needs to be set in such a way that Divorced girl can maintain the same/similar lifestyle for 9 months to one year .. this is not a set rule but a good advice that scholars give. This is for girls security.
