so, he gains a third incentive. If they command him to do so, support him on that basis, and become hostile towards him and punish him for abandoning it, he gains a fourth incentive.

For this reason, believers are commanded to counter evil deeds with their opposites among good deeds, just as a physician treats an illness with its opposite. The believer is commanded to reform himself through two things: doing good deeds and refraining from evil deeds. These are four categories.

He is also commanded to reform others through these four categories, according to his ability and means. Allah Most High says:
“By time, indeed, mankind is in loss, except for those who believe and do righteous deeds and counsel one another to truth and counsel one another to patience.”
Surah al-ʿAsr, 1–3.

It is reported that al-Shāfiʿī, may Allah be pleased with him, said: “If all people reflected upon Surah al-ʿAsr, it would suffice them.” It is indeed as he said.
