Muslim men are taught how they should beat their wives. I have seen pictures of how they are beaten lightly. The Bible teaches us to lay down our lives for our wives and love them like Christ loved the church and gave up His life for it and never to beat them. The NT Bible does not condone plurality in marriage. How many Christians do you know with 2 or more wives. Besides, Muhammad had more than 4, and there is record from his wives that they weren't treated equally. He had way more wives than his revelation permitted. As for what went on in the torah or OT bible, if you don't like it, take it up with Allah. He said he sent it to Muhammad. So you share the torah with Christians equally; so cutting down is kind of like cutting off one's nose just to spite their face. As for your statistics on Muslim converts vs Christians, I say truth is not dependent on number. Besides, Christianity has always been more numerous than Islam in the past and still in the present. It seems Allah's best of plans weren't the best when he made something false appear as real.

peace and blessing to you
