I have been meaning to write an article on this subject, it seems as though many non-Muslims misuderstand this issue. The good news is, we have somebody even better to explain the "wife-beating issue" to us. He is a popular Muslim named Yusuf Estes
Pass this information on to those who try to use the "wife-beating issue" in order to mud-sling at Islam. God-Willing they will be guided.
