What’s the difference between Jesus And Allah?

I was having a discussion yesterday with one of my older homie and my bro in law right.. well my older homie Basically said that Abraham wanted children but his wife was old and she couldn’t have children. So abraham saw the maid and was attracted to her and fornicated with her and got her pregnant. While whole time god was still following through with his promise to Abraham to give him a baby which was conceived by his wife the one who wasn’t able to have baby’s due to older age. So god ended up making abraham choose between one of the sons and the other he had to kill. don’t know which one he chose but right before he was about to kill the son god stopped his hand and wasn’t mad at abraham but told him he had to cast the maid and the son out. Which are known as the muslims, and christians the seeds of Abraham are the ones who stayed.
