[Ali Imran]

Do you remember that ISIS took Jizya from Christians in Iraq and let them live, but ISIS didn't take Jizya from Yazidis and killed their men and enslaved their women?

Here is the reason:

According to Salafi Islam (and also according to Imam Shafi'i and Imam Ahmed bin Hanbal), Jizya is allowed only for Christians/Jews/Zoroastrians (who are known as the "people of the Book أهل الكتاب" in Islam).
But as far as other non-Muslims (like Atheists, Deists, Hindus, Buddhists etc.) are concerned, then they cannot live even by paying Jizya. They either have to accept Islam, or they should be slaughtered.
Muhammad himself didn't accept Jizya from the polytheists of Arabia but after the revelation of the verse of the sword (i.e. killing all polytheists after 4 months), he forced all of them to accept Islam.
Later, some Muslim jurists like Imam Abu Hanifa and Imam Malik said that it was limited only to the polytheists of Arabia, but as far as the polytheists of the non-Arab world are concerned, they could live by paying Jizya.

But other Muslim jurists like Imam Shafii and Imam Ahmed bin Hanbal (and modern-day Salafists) disagree. According to them, non-Arab non-Muslims also don't have any right to live even through paying Jizya. They either have to accept Islam or they should be slaughtered.

This means that if Salafists form an Islamic State today, then they will kill all non-Muslims like Atheists, Buddhists, Hindus, etc. (accept for Jews/Christians/Magians who can stay alive by paying Jizya).

So you want to advance ISIS here while most Muslims reject them as extremists?
