I haven't seen any Muslims bribe anyone to convert them there in Africa... in fact.. I personally knew a teacher who told the kid if he wanted to go for the bike he should... all he could offer him was an education... guess what the kid didn't choose the bike... either way I don't think anyone can convert anyone... Not only is it a personal choice of the heart but I believe firmly that God guides whom he wills to the right path if they were sincere... you can live your whole life a miserable human being and have a change of heart and be a devout in an instance and the opposite can also be true...
if you are talking of "Ahmedis" I don't consider them Muslims... Prophet Mohammed peace be upon him warned us against sectarianism... Yet people insist on being divided.....
