The phrase referring to comes from a verse in the Qur'an, specifically Surah At-Tawbah (9:29), which addresses the relationship between Muslims and non-Muslims, particularly "People of the Book" (Christians and Jews) under certain historical contexts, especially during early Islamic rule.

Understanding the Verse:

Surah At-Tawbah 9:29 states:

"Fight those who do not believe in Allah or in the Last Day and who do not consider unlawful what Allah and His Messenger have made unlawful and who do not adopt the religion of truth from those who were given the Scripture - [fight] until they give the jizya willingly while they are humbled."

In its historical context, this verse referred to a time when Muslim political entities were in conflict with non-Muslim empires, and it established a policy for dealing with non-Muslims who lived under Muslim rule (primarily Jews and Christians). Jizya was a tax levied on non-Muslims (specifically Christians and Jews) living under Islamic governance. In return, they were allowed to practice their religion and were granted protection by the Muslim state.

Why Do Some Imams Use This Phrase?

1. Literal Interpretation: Some imams, particularly those with a strict or literal interpretation of Islamic texts, may cite this verse to emphasize a traditional understanding of Islamic law in relation to non-Muslims. They view the verse as a command for Muslims to assert authority over non-Muslim populations in the form of a tax or conversion.

2. Contextual Misuse: Unfortunately, this phrase can also be taken out of context by extremist or radical voices to promote violence or justify aggression against non-Muslims, which distorts the broader teachings of Islam that promote peace, coexistence, and mutual respect.

3. Historical Context vs. Modern Application: Many mainstream Islamic scholars emphasize that the verse applied to specific historical circumstances, such as during wars in early Islamic history, and not as a general or timeless directive for all Muslims in all times and places. Many modern scholars argue that the rules around jizya and combat with non-Muslims do not apply in the same way today, especially in societies that promote freedom of religion and equality.

4. Diversity of Opinion in Islam: Islam is not monolithic. Different schools of thought and interpretations exist, ranging from conservative to progressive. Some imams may use these verses in a more historical or political context, while others promote interfaith dialogue, emphasizing verses that call for respect and peaceful coexistence.

5. While some imams may use the phrase due to their strict interpretation of scripture, it’s important to understand that this is not the unanimous view within Islam. Most contemporary Muslim scholars and leaders focus on peaceful coexistence and reject violent interpretations of such verses. The broader Islamic teachings encourage respect for all humanity, regardless of their faith.

Then why is not been arrested for inciting violence but if another person not a moslem write or say "Islam is a terror religion" because they preach to their followers to kill anyone who's not a moslem. Islam is a cancer to our modern world and the Europeans and the world is in a big trouble with this religion.
