'Islamic terrorism' refers to terrorist acts committed by Muslim groups or individuals who are motivated by Islamic or Islamist views.
Condemned by most Muslims, Islamic terrorism is inspired by the concept of 'lesser Jihad' -- 'holy warfare' against the enemies of Allah and Islam.
The Quran states that Muslims, Jews and Christians worship the same God. However, when compared with the Jewish and Christian scriptures, the teachings of Quran show that Allah is not the same God worshipped by Jews and Christians.
In fact, neither Christianity nor Islam can logically endorse the other religion's distinctive claims and practices without denying its own.
Muslims refer to a 'greater Jihah' (the personal struggle against sin), and a 'lesser Jihad' (holy warfare against the enemies of Allah and Islam).
Muslims disagree among each other as to what is or is not acceptable in 'lesser Jihad.'
Muslims believe the Torah and the Gospel have been changed and corrupted over time.
Consequently, the Quran was needed to correct the errors in the corrupted books. It finalizes the truth from God as transmitted from the archangel Gabriel, recited by the prophet Muhammad, and written down into the Arabic language.
