Question

Who was the first person to go through as-sirat/shirath?

Answer 1

                 (NOT MY WORDS TOOK FROM A SOURCE)

It isn't known who the first person entering Angel Island was.
Angel Island was the processing station for more than 300,000 immigrants from 1910 to 1940.
For this reason it is often referred to as the Ellis Island of the West.

Hope this helped!
