(Allah (Himself) is Witness that there is no Allah save Him…) [3:18]. Said al-Kalbi: “When the Messenger of Allah, Allah bless him and give him peace, appeared in Medina, two rabbis from Syria, came to see him. When they saw Medina, one of them said to his companion: ‘How similar is this city to the city from which will emerge the Prophet of the end of times’. When they entered in on the Prophet, Allah bless him and give him peace, they recognized him by his attributes and description. They asked: ‘Are you Muhammad?’ ‘Yes!’ He answered. ‘And you are also Ahmad?’ He said: ‘I am!’ They said: ‘We will ask you about witnessing; we shall believe in you if you do inform us about it’. The Messenger of Allah, Allah bless him and give him peace, said: ‘Do ask me!’ They said: ‘Tell us about the greatest witness in Allah’s Scripture’. Allah, exalted is He, revealed to His Prophet (Allah (Himself) is Witness that there is no Allah save Him. And the angels and the men of learning (too are witness)…). The two men embraced Islam and believed in the Messenger of Allah, Allah bless him and give him peace”.
