"O my son! Aqim-is-Salat (perform As-Salat), enjoin (people) for Al-Ma'ruf (Islamic Monotheism and all that is good), and forbid (people) from Al-Munkar (i.e. disbelief in the Oneness of Allah, polytheism of all kinds and all that is evil and bad), and bear with patience whatever befall you. Verily! These are some of the important commandments ordered by Allah with no exemption.
