A central slogan in your posts on YT/blog seems to be "muhammad lied".
I don't believe he lied,- that would be too extremely hard to keep on lying 23 years. Especially lying (in order to gain wordly things) doesn't make sense during the Meccan period, in which Muhammad was poor and had few followers.
No,- Muhammad honestly believed what he preaches, i.e. he was not a liar, but rather schizophrenic.
If prophets had lived today, they would all be in mental hospitals.
I also don't believed he consciously lied, but I don't think he was schizophrenic either. A schizophrenic cannot be coherent and hold it together enough, nor manage his and others affairs so shrewdly as Muhammad did.
He was just one of many at that time who believed God spoke to him, but he had the charisma and naturally manipulative personality to carry it of a bit better - and got lucky in the sense that he was in the right place at the right time for his utterances to be believed and when the desert Arabs were ready to emerge from the desert.
