Did anybody find somewhere in the Islamic law that a Qadhi can nullify a properly solemnised legal marriage of a Muslim couple after awhile when they already have children born of that legal marriage?
Has Saudi Arabian culture been given preference to Shariah?
It seems then, all those people married and settled in S. Arabia, can be unsettled anytime if I was to approach a Qadhi and convince him the bride and the groom are not equal and ask for anullment of marriage.
And what about the children who are already born?
It is perfectly understandable why the media take these 'samples' of "muslim country laws".
Or is it not true story. We are left confused sometimes but if it is true story:
"cho kufr az ka'ba berkhaized kuja manad musalmani" (When disbelief springs from the ka'aba itself what is left of Musalmani or Islam)
