“O my dear son! Establish prayer, encourage what is good and forbid what is evil, and endure patiently whatever befalls you. Surely this is a resolve to aspire to.

"O my son! Aqim-As-Salât (perform As-Salât), enjoin (on people) Al-Ma‘rûf - (Islâmic Monotheism and all that is good), and forbid (people) from Al-Munkar (i.e. disbelief in the Oneness of Allâh, polytheism of all kinds and all that is evil and bad), and bear with patience whatever befalls you. Verily, these are some of the important commandments (ordered by Allâh with no exemption).
