(Call unto the way of thy Lord) the religion of your Lord (with wisdom) with the Qur'an (and fair exhortation) exhort them with the exhortations of the Qur'an, (and reason with them in the better way) with the Qur'an; it is also said that this means: by means of “there is no god but Allah”. (Lo! thy Lord is best aware of him who strayeth from His way) from His religion, (and He is Best Aware of those who go aright) to His religion.
