Enjoining the Good and Forbidding the Evil

{3:104} And from among you there should be a party who invite to good and enjoin what is right and forbid the wrong, and these it is that shall be successful.

Comment: It is easier to accomplish this goal if good people work in groups.

{9:67} The hypocritical men and the hypocritical women are all alike; they enjoin evil and forbid good and withhold their hands; they have forsaken Allah, so He has forsaken them; surely the hypocrites are the transgressors.

{9:71} And (as for) the believing men and the believing women, they are guardians of each other; they enjoin good and forbid evil and keep up prayer and pay the poor-rate, and obey Allah and His Messenger; (as for) these, Allah will show mercy to them; surely Allah is Mighty, Wise.

{31:17} O my son! Keep up prayer and enjoin the good and forbid the evil, and bear patiently that which befalls you; surely these acts require courage;

{4:85} whoever joins himself (to another) in a good cause shall have a share of it, and whoever joins himself (to another) in an evil cause shall have the responsibility of it, and Allah controls all things.
