Syakh Abdul Aziz bin Abdullah bin Abdur Rahman ar-Rajihi

It’s incumbent for the Muslim to be concerned with renewing his ʾIman (i.e., correct Islamic faith) in the evening and the morning by pondering on the meaning of the statement of Tawḥid la ilaha illa Allah since there’s no success except for the people of Tawḥid. For it is the statement of Islam. So, the Muslim (Muwahhid) must learn about Tawḥid, implement it, be aware of its position, reject Shirk which is the opposite of Tawḥid, have a hatred for associating partners with Allah as well as those who practice it. The Muslim must deem the one who commits major Shirk (knowingly) is a disbeliever of the true Islāmic Faith. The Muslim must also be aware of the position of Shirk.
