Safiyyah Ally:
The first question we have is: how do Muslims know about Adam, or where do they get the story from?
Dr. Shabir Ally:
Well, basically we get this information from the Quran, which Muslims believe to be a revelation from the Almighty God.
It’s similar to the Bible in many respects and it gives us many of the biblical stories. But often in a very truncated or elusive form.
It just refers to the story on the assumption that people already knew these stories and brings out new moral teachings from them.
I hope this helps answer your question. Please keep in touch.
Walaikum Asalam.
