How do we respond with a strong and convincing argument to someone who, when enjoined to do good or forbidden from evil, invokes Allah's saying: "O you who have believed, upon you is [the responsibility for] yourselves"?

The interpretation of the noble verse, "O you who have believed, upon you is [responsibility for] yourselves. No harm will come to you from one who goes astray when you have been guided," does not mean that enjoining good and forbidding evil is not obligatory. Rather, it is understood from it that this applies after expending effort in enjoining and forbidding without success. The guidance mentioned in the verse includes enjoining good, and whoever abandons this is not guided. What confirms this is His — the Almighty's — saying: "By time, Indeed, mankind is in loss, Except for those who have believed and done righteous deeds and advised each other to truth and advised each other to patience." Furthermore, verses and hadiths have warned that abandoning enjoining good and forbidding evil leads to a universal punishment. On the authority of Abu Bakr Al-Siddiq, may Allah be pleased with him, he said: I heard the Messenger of Allah, may Allah's prayers and peace be upon him, say: "If people see an oppressor and do not restrain him, Allah will soon afflict them all with a punishment from Him."
