Translation:

92. And to rehearse the Qur'an: and if any accept guidance they do it for the good of their own souls and if any stray say: "I am only a Warner."

Notes (Tafseer)

3323. The duty of the Prophet and his adherents was, first, to accept Islam and become themselves shining examples of Allah's grace and mercy, as they in fact were, and secondly to preach that message and spread that Light to all around. It was not for them to force it on unwilling people: for any who rejected it would find their own spiritual loss in such rejection. But they must clearly warn them of the consequences.
