Re: GS Religion Forum [Q & A]
Oh I am sorry, I did not read your first question poperly. I dont remember the name of Sahabi but he was from Ansaar and a jew scholar.
When Jews came to prophet 
and tried to save one of thier woman from the punsihment of adultry and presented Torah as prove, that ex-jew sahabi pointed out the ayaat of Torah that mentioned Rajm as punsihment,
for the first Hindu, should not that be the Raja who witnessed Shaq-ul-Qamar from his palace in India
