Translation of the verse 17 from Surah Luqman : Number of verses 34 - - page 412 - Part 21.
"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.
O my son, establish prayer, enjoin what is right, forbid what is wrong, and be patient over what befalls you. Indeed, [all] that is of the matters [requiring] determination.
(31:17) Son, establish Prayer, enjoin all that is good and forbid all that is evil, and endure with patience whatever affliction befalls you. *29 Surely these have been emphatically enjoined. *30
*29) In this there is a subtle allusion to this that whoever will enjoin good and forbid evil, will inevitably have to face and undergo afflictions and hardships in the world.
*30) Another meaning can be: "These are things which require courage and resolution. To rise for the reformation of the people and to brave the hardships of the way cannot 1>e the job of a mean-spirited and cowardly person."
