What each and everyone of us must do is to learn Islam, from scratch as it were, and to preach and teach it to everyone everywhere in the world.
This is the job for which Allah created us in the first place.
As the Qur'an says, in a different context:
Wa Lidhaalika Khalaqahum!
And that requires total and unflagging focus on the part of each and everyone of us.
And that requires that each and everyone of us put everything else on the back burner, whether it is our jobs, businesses, relatives, parents, children, everything.
If we don't do it, the results will be disastrous -- for us and for the world.
And that is precisely what is going on in the world right now.
