“…The power of jihad as a motivating factor for a man like Bouhlel should not be underestimated.
In popular culture, the idea of the jihadi dying for the sake of the 72 virgins he will receive in the afterlife is a common one. While undoubtedly some are motivated by this vision, I think many jihadis are more driven by fear of their own sinfulness.
Amongst good deeds that Muslims can do, jihad is unique. Its special characteristics are described in the hadith of Sahih al-Bukhari.”
