“Our Lord! indeed, we believed with what You have sent down and we have followed the Messenger, so you enroll us with the witnesses”.
“The Messenger” mentioned is Jesus for the disciples of Jesus. But this verse is also a declaration of a Christian gang who came to Medina from Najran under the leadership of Adiyy-Ibnu-Hathim to see Messenger Muhammad. So, in that case, “the Messenger” mentioned applies to Muhammad also. It is told in verse 5: 83: “When they (monks and priests) listen to that which is revealed to the Messenger, you can see their eyes filled with tears because of what they recognize from the Truth. They say: ‘Our Lord! We believed. Therefore, You enroll us among the witnesses of Truth’”. It is told in verse 57: 19: “Those who believed with Lord and His Messenger are the truthful and witnesses with their Lord. They have their reward and their Light, those who disbelieved and rejected Our verses, they will be the inmates of Hades”. Anyone from the groups of Arabic Quran reading Fujjar if hides or rejects the Witness Adhikr, then Fire is promised to him as told in verse 11: 17. See explanation 2: 38-39 and 17: 107-109.
