Were anyone waiting for the return of Easa عليه السلام for 550-600 years before the elevated Messenger Muhammad,

• Know the fact that as soon the Book-Qur'aan through the Messenger came to them from Allah the Exalted; they refused to accept it.

• This Book is the Testifier-Affirmer-Certifier-Sanctifier of that which they already had with them.

• And in the earlier time line they were desperately praying-aspiring for comprehensive victory [on arrival of Nabiuemm'mi and Book] over those who were the Non Believers.

• Thereby, when it was brought-came to them which they recognized, they refused to accept it.

• Sequelly, the Curse and Condemnation of Allah the Exalted is hovering upon those who have deliberately and persistently refused. [2:89]
