Each of these four divisions is divided into types, as will be explained, Allah willing.
Know—may Allah teach us and you what we do not know and benefit us and you by what we know—that believing in the outward forms [Zahir] of these limits and performing them in private as a matter of faith is strictly forbidden. However, performing them among their people [the public] as Taqiyya is religiously mandatory; for there is no religion for the one who has no Taqiyya.
Allah the Exalted said: {On the Day when the hypocrites, men and women, will say to those who have believed, "Wait for us that we may acquire some of your light." It will be said, "Go back behind you and seek light." So a wall [Sūr] will be placed between them with a gate, its interior containing mercy, but on the outside of it is punishment. They [the hypocrites] will call to them, "Were we not with you?" They will say, "Yes, but you afflicted yourselves and waited and doubted and were deluded by false hopes until the command of Allah came, and the Deceiver [Satan] deceived you about Allah"} (Al-Hadid 13-14).
