The Koran isn't usually considered a humorous book because of all the hatred and intolerance it contains. And it paints a picture of Allah as a deity that is petty, and vindictive, and jealous of his power. He'll only do good things for you if you kiss his ass. Not surprising that a prophet that was a highway robber, a mass murderer, a slaver, a killer of his critics, a pedophile, a wife abuser and a warlord would create a deity like that.
But there are two passages in the Koran that I find funny.
The first is when Mohammed was starting his cult in Mecca. Not every Arab who lived during his time was stupid or venal, and there were Arabs who told him he was spewing a bunch of camel shit. His response - he channeled a verse in the Koran saying that he was the prophet of Allah, and they would be sorry for doubting him. I always laugh when I think of this. They were lucky it wasn't later, because after he had his gang of thugs, he would have his critics assassinated.
The second is when Mohammed arrived in Medina, and had gathered his gang of thugs. He heard about a tribe wandering in the desert, and took his gang of thugs to confront them. He told them they could tithe (10 or 20) percent of their wealth and join his cult, or he would kill and enslave them. In other words, an offer they couldn't refuse, in fitting with his new status as warlord. They refused, and he and his gang killed all the men, and enslaved all the women and children. Just like ISIS did to the Yazidis. Mohammed noticed a woman in the slave pen that he lusted after, but he already had his full quota of wives. But, lo and behold, he had an instant revelation from Allah that the prophet (that's him!) wasn't subject to any sexual limitations, so he got to keep her. What a way to sweep a girl off her feet! What a charmer! I always laugh at the instant revelation from Allah. The gang of thugs had to know it was all fake, but of course they got to keep sex slaves and a share of the loot, so they went along with him. Well, maybe some of them were stupid enough to believe him, because inbreeding in Arabs didn't start with the cult of Islam; it just codified the practice by allowing first cousins to marry. It's astonishing that herders would adopt such a harmful practice, but stupidity is.
Just one more funny story about the cult, though it isn't from the Koran. After Mohammed died, the cult went on an orgy of killing and enslaving. Of course, they had to fight battles. Before one of these battles, the then calif believed the Koran when it says that Allah will defend and protect the Koran. At that time, there was no written Koran, it was all kept in memory by mostly warriors. This calif reasoned that if he sent all those warriors who had memorized the Koran into battle, they would surely win, because Allah would aid them to protect the Koran. So he did, and they were massacred. Whole sections of the Koran were lost because the only people who had them memorized were killed. Did this open his eyes? Did he suddenly realize he was a brainwashed fool? No! He doubled down by having the Koran put in written form.
Anyone not growing up brainwashed and threatened by the cult has to be willfully stupid to believe crap like this.
