How do we respond to those who caution against enjoining good and forbidding evil, citing Shuʿayb's saying, "And I do not wish to be at odds with you," and Allah’s saying, "O you who have believed, upon you is [responsibility for] yourselves"?

In the two verses: (O you who have believed, upon you is [the responsibility for] yourselves. Those who have erred will not harm you when you have been guided) and (Do you order [other] people to righteousness and forget yourselves?), there is no argument for someone who warns against enjoining good and forbidding evil.

The first verse (Do you order [other] people to righteousness) does not condemn enjoining good; rather, it condemns the neglect of acting upon it. Enjoining good and acting upon it are both obligations, and the neglect of one does not nullify the other. A Muslim must enjoin good and forbid evil, even if they are not fully committed to them, because abandoning the call to goodness impedes a pillar of the religion.

As for the second verse (upon you is [the responsibility for] yourselves), its context is a time when people turn away from accepting advice and when there is no benefit in enjoining good and forbidding evil. This time has not yet come. The sacred texts urge enjoining good and forbidding evil as long as there is an expected benefit, and this obligation does not cease except in cases of inability or fear of severe harm.
