Say: “O people of the Scriptures, your only way to success is to follow the [original] Torah, the Gospel and the other Books which God has sent to you [which, by the way, are the same teachings that you will find in Qur’an and, therefore, there will not be any question of “changing” your religion but instead following it in the most proper manner.]” However, these revelations (Qur’an) will instead increase the rebellion and the disbelief of many of them [as they do not keep an open mind.] It is not, therefore, worth it for you to feel sorry for the disbelievers [as they have made a conscious choice.]
