Waraqah ibn Nawfal, the cousin of Khadijah (ra) was a Christian and a
man of faith. His words to the Prophet (s) when he first received
revelation show us the loyalty we should have to the Message and the
Messenger:
"I wish that I were still young. I hope I will still be alive when
your people drive you out!" The Messenger of Allah (sallallahu `alayhi
wa sallam) said, "Will they drive me out?" He said,"Yes, no man has
brought anything similar to what you have brought without being
treated with hostility. If I am still alive on that day, I will give
you my strong support."
[Sahih Muslim]
