The Ruling on Calling to Allah and the Criterion Therein

Question:
Honorable Shaykh, can everyone call to Allah? And what is the criterion for that?

Answer:
We have said that every Muslim calls to Allah according to his ability. He says, "O so-and-so, you have an error such and such, so fear Allah." If you have a doubt, ask the people of knowledge. It appears to me that this is not permissible. If you have a doubt about it, ask the people of knowledge and do not remain with this action, or this statement, or this observation.
As for the issue of issuing fatwas and what is lawful and forbidden, no, this is not done by anyone but the people of knowledge. But the issue of saying, "O so-and-so, fear Allah; O so-and-so, pray; O so-and-so, maintain obedience to Allah; O so-and-so, remember death, remember the Hereafter"—all of this is something even the common people can do. As for the issue of what is lawful and forbidden, the obligatory, the forbidden, the recommended, and the disliked, this requires the scholars. Yes.
