The Greatest Witness
In later times, this dawah mission was to spread all across the world. This development is referred to in the Hadith as shahadat-e-aʿzam, that is, ‘the greatest witness’. The Prophet of Islam had said that a time would come when it would become necessary to perform the work of dawah with rational arguments (hujjat). Those who present the message of God by employing arguments that are in accordance with the rational standards of their time will be held deserving of great reward by God. The dawah of such people is referred to in a hadith in these words: “This is the greatest witness in the eyes of the Lord of the Worlds.” (Sahih Muslim, 2938)
