Hashim Amla, in my opinion, is already in safe hands (his shaykh), why do you think he should be given dawah to spend time in jam'at? At the end of the day, it all comes down to getting one's Islah done, be it through dawah/tableegh or islahi relationship with a Shaykh, which he's already into. He is doing a great job by representing Islam to a much wider audience with his actions on & off the ground, something that you and I together wouldn't be able to do. He is a Daee in himself, bro. I don't understand why do we wish everybody to spend time in khrooj.
