Excuse me, but how do you know that they hijacked term "jihad"? Should I quote Quran verses to you?
for example
"[2.190] ...fight in the way of Allah with those who fight with you...[2.191] And kill them wherever you find them, and drive them out from whence they drove you out, and persecution is severer than slaughter, and do not fight with them at the Sacred Mosque until they fight with you in it, but if they do fight you, then slay them; such is the recompense of the unbelievers. "
..whoever flies in Allah's way [forsakes his home to fight in Jihad], he will find in the earth many a place of refuge and abundant resources, and whoever goes forth from his house flying to Allah and His Apostle, and then death overtakes him [in Jihad], his reward is indeed with Allah...[4.101] Rodwell: And when ye go forth to war in the land, it shall be no crime in you to cut short your prayers, if ye fear lest the infidels come upon you; Verily, the infidels are your undoubted enemies! [4.102]...let them take their arms...let them take their precautions and their arms...there is no blame on you, if you are annoyed with rain or if you are sick, that you lay down your arms...[4.103] Khalifa: Once you complete your Contact Prayer (Salat), you shall remember GOD while standing, sitting, or lying down. Once the war is over, you shall observe the Contact Prayers (Salat); the Contact Prayers (Salat) are decreed for the believers at specific times.[4.104]...be not weak hearted in pursuit of the enemy...
There peaceful verses, and there were not many of them, were later abrogated. **
** abrogated means that the earlier verses give way to later. Earlier, peaceful verses deal with the period of time when Mahomet and his followers were in minority (Mecca period), later they were in majority (Medina period). So for examples in earlier verses Muslims could drink wine, later verses abrogated that, and so on and so forth.
