Let’s go back to the beginning of islam. How did islam come to life? It all started with a man in a cave. After spending several days in solitude in the cave, muhammad falls asleep. He then claims that he sees a figure, trying to strangle him three times.
Narrated by ‘Aisha:
… suddenly the Truth descended upon him while he was in the cave of Hira. The angel came to him and asked him to read. The Prophet replied, “I do not know how to read. The Prophet added, “The angel caught me (forcefully) and pressed me so hard that I could not bear it any more. He then released me and again asked me to read and I replied, ‘I do not know how to read.’ Thereupon he caught me again and pressed me a second time till I could not bear it any more. He then released me and again asked me to read but again I replied, ‘I do not know how to read (or what shall I read)?’ Thereupon he caught me for the third time and pressed me, and then released me and said, ‘Read in the name of your Lord, who has created (all that exists) has created man from a clot. Read! And your Lord is the Most Generous.” (Sahih Bukhari Volume 1, Book 1, Number 3)
Now, Ibn Ishaq’s famous early biography of Muhammad, sirat-rasul, clearly states that Muhammad was sleeping when having this “vision”.
So I [Muhammad] read it, and he [Gabriel] departed from me. And I awoke from my sleep, and it was as though these words were written on my heart… 
The same above hadith say the exact same thing
Narrated ‘Aisha: (the mother of the faithful believers) The commencement of the Divine Inspiration to Allah’s Messenger (ﷺ) was in the form of good dreams which came true like bright daylight, and then the love of seclusion was bestowed upon him… (Sahih Bukhari Volume 1, Book 1, Number 3)
- Question number one – did he actually see an angel? No, he did not. He had a dream.
- Question number two – did muhammad have anyone around to confirm his experience? Any eye-witnesses? No, he was alone in the cave.
- Question number three – did the person trying to strangle him, ever explain who he/it was? No.
Mohammad, now being fully convinced that he is possessed, tries to hurl himself off a cliff and commit suicide . Then he starts to hear voices, telling him that “he is an apostle of god”.
“While I was walking, all of a sudden I heard a voice from the sky. I looked up and saw the same angel who had visited me at the cave of Hira’ sitting on a chair between the sky and the earth. I got afraid of him and came back home and said, ‘Wrap me (in blankets).’ (Sahih Bukhari Volume 1, Book 1, Number 3)
Again – nobody can confirm what he heard. No witnesses.
Muhammad was asked numerous times to confirm his prophethood by signs, but was unable to do this. He was “only a warner”.
Islam is false. Allah is a fabricated god made up by a false prophet.
