I’ve read opinions saying that Islam needs the kind of reformation that Christianity went through. Maybe so.
But I don’t think so.
For one thing, you could argue that Islam (at least Sunni Islam, the faith of over 80% of all Muslims) has already had a reformation. Its Martin Luther was 18th-century cleric Muhammad ibn Abd al-Wahhab, who wanted to “purify” Islam and preached a hard-core fundamentalist approach. Today, Wahhabism in one form or another seems to influence ISIS, al-Qaida and other extremist Islamists.
If you don’t buy Wahhab as Luther, consider this: Why should Islam follow the Christian model at all? I don’t think that Buddhism, Hinduism, Judaism, or other major faiths have gone through a Christian-style reformation. They’ve changed and evolved in their own ways. So has Islam, for that matter.
Either way, I wouldn’t stay up nights waiting for a 21st century Islamic reformation.
