Muhammad, according to the standards of the world was a winner, as he had claimed loads of land and wives and possession. But he died like every other loser. No profound resurrection. He was a prophet who wound up worm food like Hosea, Moses, and all the others.
If we judge Jesus's success by historical success, nah. In fact, his name probably got the damnatio memoriae treatment (similar to how Egyptian pharaohs sometimes had their names wiped from records). He had to exist though, because people don't spontaneously become a sect without a leader. But yeah, he died in obscurity, having failed within his lifetime to make any dent.
Or did he? Muhammad's legacy was centuries of conquest, anyone who is an honest historian can tell you Islam means submission. But very little real advances besides their religion. No sorry, there are not 1001 advances in science, though there are many things they took credit for. But it created little impact on the quality of life.
But we're talking about actual advances. The US and Europe ended slave ownership, yet gets beat over the head for their involvement in the slave trade. Why are Muslims never called to pay reparations? They were also involved in the slave trade yet never did a thing to end it. In fact, the first thing that happened after Christianity is that Paul asks one of the slaves who has converted be freed. This was only years after Christ, ppl are thinking seriously about the ethics of slavery. And women, rather than being seen as shameful (ahem) are told that a husband's duty is to obey and cherish his wife. Rather than being part of a harem, women are gradually able to inherit property and to vote. And when we're talking about advances, here's one that happened in a Christian nation. The Magna Carta. Or how about the US Constitution (and yes, ppl will say that it's a secular document but here's the response to that:
Does God Appear In The United States Constitution? ). Here's another. Medicine. It used to be that Christian missionaries and medics went hand in hand together overseas.
Even without these, let's look at Rome around the time of Jesus. It's a brutal efficient killing machine that regularly crucified ppl, that had perfected a tax system, and who had a military system that even had Jewish priests in its pocket (notice the coin the priests showed when Jesus said "render unto Caesar", it wasn't the Jewish coin given as tax, it was a Roman coin with Caesae's image and inscription ). And yet, after his death, people are noticeably unafraid to die. Christians are brought to the wine and circuses to fight wild animals or get tortured to renounce their faith, but they actually manage to make Roman converts. Suddenly, this system of conquest and terror is taken apart by the very people who are supposed to be like "yeah you guys are right, we were just imagining things" and who are supposed to be cowering. But they're not. Oppressive people always try to bully others into agreeing with their thinking, but they always collapse under their own excesses. Roman became decadent, and these Christians became such a force that many Roman officials were converts. Including much of the Roman guard. 40 centurions were made to stand in a freezing cold pond until they renounced Christ. Naked. They stripped willingly and went to the pond. It took centuries, but eventually the Roman Empire gets taken over by the Germans and becomes dismantled, as the Holy Roman Empire, a group of city-states that have relative autonomy. From there this Roman Empire gradually becomes separate nations with national identity.
I want you to take a look at what's going on now. Muslims have not changed in centuries, but neither has their quality of life. In fact, liberal areas where they have cultural relativism, and decided all immigrants are equal, are suddenly infested with bubonic plague and ebola. Meanwhile the West before this rush for immigration and globalism, believed in globalization, something completely different. They traded with other countries mixing ideas, and coming up with advance after advance. In the time of Jesus, ppl slept on the floor, and often lived in caves. By the 1800s they had beds with metal coils and heating for winter months. Now they have central HVAC systems, soft beds, bed bugs until recently (made a comeback) were largely just an expression.
One of these religions encouraged ppl to be seen as actual humans with creature comforts, and desire to buy things for themselves. The other had a leader who only cares for his OWN comfort.
