Wa `alaykum as-salamu wa rahmatullahi wa barakatuh.

 

I don’t know where this ruling or opinion comes. We cannot make judgments in religious matters based on speculation or whimsical reasoning.

 

As for our duty to spread the message of Islam, we ought to do so through our character and interaction with people exposing them to the beauty of religion rather than preaching.

 

It was mainly through their openness and peaceful interaction with people. That was the way Islam spread in most of those countries where Muslims are now in the majority without any soldier going there.

 

Almighty Allah knows best.
