So if your a Muslim and you nothing about Sharia law which is set down in the Qur'an and by the prophet Muhammad doesn't that make you a bad Muslim?
no not really. let me explain:
I know it to my understanding that interest is not permitted, thats what Sharia law is I think. I dont take loans from bank and all the interest I get from my accounts go to charity.
If I take drugs, and drink Alchahol and do other sins that are well knowen in christianity, judaism and islam. Then that makes me a bad muslim as am defiying laws in my religon.
) were to be introduced. Now you have to make a decision, do you allow someone else's faith in a God to influence how you live?
