Please try and not send any links that are Islamic in Origin as they will most likely be very very biased.

Sure, but that doesn't make them useless. Nor are they necessarily more biased than non-Muslim accounts of early Islam. Navigating different biases is something that every student of history must learn to do.

The overwhelming majority of information that we have about Muhammad ﷺ and his life comes from Muslim biographers, historians, and hadith collectors. Still, if you're only interested in non-Muslim accounts, you're in luck. Robert Hoyland compiled a great deal of these in Seeing Islam as Others Saw It: A Survey and Evaluation of Christian, Jewish and Zoroastrian Writings on Early Islam (1997). It's an excellent book. You can find a full copy on Scribd very easily by googling the title and the author's name. I'd link to it directly, but I'm not sure if that's against the subreddit rules.
