Until the advent of materialism and 19th c. dogma, Western Civilisation was superior to anything Islam had developed. Islam has not aided in the development of the modern world; in fact civilisation has only been created in spite of Islam. Proof of this resides in the 'modern' world and the unending political-economic and spiritual poverty of Muslim states and regions. Squatting on richer civilisations is not 'progress'. Islam is pagan, totalitarian, and irrational.
The Hadith certainly prescribe fighting and killing in the name of the Allah. To engage in Jihad and murder, kill, crush, or humiliate Christians and Jews is a Moslem obligation. All claims to the contrary are lies. Consider the 'Jihad chapter' of the Hadith by the ever-celebrated Abu-Dawd, one of the 'great' Moslem chroniclers. Some of his odes to Jihad include:
Jihad ensures your salvation:
2493 Narrated AbuMalik al-Ash'ari: AbuMalik heard the Apostle of Allah say: He who goes forth in Allah's path and dies or is killed is a martyr, or has his neck broken through being thrown by his horse or by his camel, or is stung by a poisonous creature, or dies on his bed by any kind of death Allah wishes is a martyr and will go to Paradise.
Join the Jihad or at least take care of the families of those who fight:
2497 Narrated AbuUmamah: The Prophet said: He who does not join the warlike expedition, or equip, or looks well after a warrior's family when he is away, will be smitten by Allah with a sudden calamity. Yazid ibn Abdu Rabbihi said in his tradition: 'before the Day of Resurrection".
To strive means to fight in Jihad:
2506 Narrated AbuAyyub: AbuImran said: We went out on an expedition from Medina with the intention of (attacking) Constantinople. AbdurRahman ibn Khalid ibn al-Walid was the leader of the company. The Romans were just keeping their backs to the walls of the city. A man (suddenly) attacked the enemy. Thereupon the people said: Stop! Stop! There is no god but Allah. He is putting himself into danger. AbuAyyub said: This verse was revealed about us, the group of the Ansar (the Helpers). When Allah helped His Prophet and gave Islam dominance, we said (i.e. thought): Come on! Let us stay in our property and improve it. Thereupon Allah, the Exalted, revealed, "And spend of your substance in the cause of Allah, and make not your hands contribute to (your destruction)". To put oneself into danger means that we stay in our property and commit ourselves to its improvement, and abandon fighting. AbuImran said: AbuAyyub continued to strive in the cause of Allah until he (died and) was buried in Constantinople.
If you fight for Allah you will be resurrected:
2513 Narrated Abdullah ibn Amr ibn al-'As: Apostle of Allah, tell me about jihad and fighting. He replied: Abdullah ibn Amr, if you fight with endurance seeking from Allah your reward, Allah will resurrect you showing endurance and seeking your reward from Him, but, if you fight for vain show seeking to acquire much, Allah will resurrect you making a vain show and seeking to acquire much. In whatever you fight or are killed, Abdullah ibn Amr, in that state Allah will resurrect you.
The above injunctions are clear. Jihad means to fight and conquer the 'enemy'. Striving in the name of Jihad means to sacrifice everything you have for the Allah-idol or Meccan moon deity [and Muhammad]. So when a Catholic priest, an Anglican clergy, a Roman curia, an Orthodox minister or any other Church leader claims that the Koran, the Hadith, and perforce Islam, forbids Jihad, war, death and civilizational struggle you can rest assured that they are illiterate and ignorant.
