Have you ever considered the similarities between Mongolian conqueror Genghis Khan and Arabian conqueror Mo? If not then look at the facts:
Changez Khan told his people that god Tengiri chose him as their leader had assigned him and his people to conquer the whole world and that Tengiri promised to help them in achieving their goal. Mo told his people that their god Allah had made him his prophet and had assigned him to convert every one to Islam. He told them Allah had promised to send angels to fight infidels and that one day Muslims will rule the whole world.
Tengiri said any community which did not go along with his order, was to be annihilated, their property to be looted, their women to be enslaved and raped. Allah said any community which did not convert to Islam was to be attacked, their lands captured, booty taken, people enslaved and captured women raped.
Changez got his revelations from Tengiri in his fits, his secretaries noted down what he said in his fits. Mo got his revelations from Allah during his fits and his secretaries noted them down.
Changez and his hordes annihilated every community which resisted them, killed armed men, enslaved others and distributed captured women among themselves and raped them. Changez got to sleep with the most beautiful ones and often slept with the wives and daughters of the enemy chiefs.

Mo and his hordes attacked every community which refused to convert, killed many, enslaved others, distributed captured women among themselves and raped them. Mo took the best looking one and often the wife of the Chief (Rehana, Safia, Juavaria etc.)

Changez was known to have super sexual powers. He could sleep with many women every night.
Mo was known to have sexual strength of many men. He used to have sex with all his wives numbering more than ten and his concubines and slave girls in the same night.

Mongol hordes captured half the world in a short time, killed, raped and enslaved millions, all that in the name of god Tengiri.
Muslim hordes captured half the world in in a short time, killed, enslaved and raped millions, all that in the name of god Allah.

Tengiri had set very strict moral rules for Mongols to deal with each other but there were no rules when dealing with the enemy. They could plunder, loot and rape others but even petty stealing from or lying to a Mongol was punished harshly.
Allah did not mind looting caravans, plundering peaceful communities, massacring infidels and enslaving and raping innocent non-Muslim women but punished petty theft from a Muslim by cutting hands, drinking alcohol with whipping and adultery with a Muslim with stoning.
Changez and his hordes sincerely believed that they were doing god's work when they were killing plundering. He used to say to his victims that it was god's punishment to them because they resisted and thus went against god's wish.
Mo and his hordes sincerely believed that they were doing god's work when they were killing and plundering. Allah in Koran said, it is not you killing but it is god killing with your hands. He also said booty and captured women are halal for you.
Changez was an exceptional politician, and a brilliant military leader. He was able to unite all Mongol tribes in a powerful army. They came from all over to join hands with Changez to attack surrounding countries with blessing of god Tengiri in the lure of loot and enemy women. Mo was an outstanding politician and a brilliant military man. His idea of Jihad was a master stroke in the human history. Live and enjoy booty and captured women. Die and go to heaven and have sex with perpetually virgin big bosomed maidens. Arabs came from all over Arabia in the lure of booty and beautiful women. At times he had to turn away potential jihadis.
Changez died at age 62 or 63 from long term effects of fall from a horse in one of the campaigns. Mo died at age 62 or 63 from long term effects of poisoning during Khyber campaign.
Doesn't it seem that Tengiri was the same Deity as Allah and Jehovah, and Changez was one of the prophets like Mo and Moses. Perhaps descendant's of Changez Khan realized it eventually and after giving Mo's disciples a taste of their own medicine for many years, decided to convert and join hands with Muslims, and went after India to do god's work there.
