if you knew history believer, those temples changed into Mosques, this happaned when It became a Muslim country! they didnt destroy it
Yes 'Believer' Islam has come to remove falsehood and there are more letters from Muhammad peace be upon him. All Islamic leaders went to invite others to accept Islam. In case they refuse, they still had a chance to pay the 'protection tax' and if they still refused, they would be conquered. But this doesnt mean that they lose their rights... in fact everyone was free to keep their own religions. Jews, Christians and Muslims lived together in peace. The conquest was the way at that time to bring the message of Islam into a foreign land.
Amamzingly, the largest Muslim county isnt an Arab country but its an 'indo-chinese' country! Now the number of converts to Islam in western countries esp. the States is amazing!
