Sheikh ibn Uthaimeen رحمه الله تعالى said:
“It is obligatory upon a person to begin with his own self by enjoining upon himself that which is obligatory, thereafter forbidding himself from all that is sinful.
The one that has the most right to be fulfilled after the rights of the Messenger صلى الله عليه و سلم , is your own self.
BEGIN WITH YOUR OWN SELF ‼
Prevent your nafs from exceeding the boundaries‼
If this is implemented, you are Hakim – Wise.”
