Storekeeper changes robber’s religion

I haven't seen anything that would indicate that the shopkeeper actively solicited the conversion. I agree, the robber was most likely trying to ingratiate himself to the shopkeeper in an effort to avoid police involvement or whatever, but that hardly changes the noble nature of the shopkeeper's actions.

If you read the actual articles about that, you'll see that most of the "drug paraphernalia" he was caught were actually hookahs, which are generally associated with tobacco, not marijuana (especially in Pakistan and the Middle East). As for the 6 bongs he was selling (yes, that's all they found)...I'd be shocked if my parents, who in all likelihood are far more educated and westernized than Mr. Sohail, knew what a bong is customarily associated with. So while I'm not convinced that he didn't know what he was doing, I don't think its as absurd and implausible as you wish it was.
