The Hadith is the collection of the sayings of Muhammad throughout his life which are authoritative for Sunni Muslims. Not only are the sayings of Muhammad filled with historical errors, but they contain many scientific ones that are completely absurd.
To give one example of this, I encourage you to watch this video by David Wood on Muhammad’s fly-wing medicine:
The rest of his “Fun Islamic Facts” videos are both hilarious and tragic at the same time. They are hilarious because these beliefs are so utterly contrary to what we know about the world and they are tragic because there are over 1.6 billion Muslims in the world who are heading for hell believing in a false religion that is so easy to disprove. But Muslims cannot see this because they are blinded to the truth by Satan and their own hearts (2 Cor 4:4). Their problem is not merely a lack of evidence, but the lack of a new heart. Let’s pray that God would use us to be his instruments to bring the gospel to Muslims and others who need to hear the message we have.
