Neither do I - but it played a big part in my life - so I know more bits (good and bad) than I do about say.. Christianity, Hinduism or Buddhism which I'm sure also contain a great many wisdoms.
Go on then. As you suggest you have been influenced by Islam, let us know in what way that you probably would not have done otherwise e.g. as an Egyptian/Englishman without Islam.
Actually come to think of it, I can think of a way that you may have but would still be interested to see your opinion.
I think it is different for you as you made some life decisions based on Islam, whereas I left Islam in my teenage years and since then actively tried to get some balance by exposing myself to lots of different cultures & ideas.
I also dont really see Islam as a culture, but as a religion, which mostly talks about how you should relate to God.
