Those messengers, We had made some to excel others. Among them were those to whom Allah spoke and some of them He exalted in degrees. And We gave to Isa, the son of Maryam, clear proofs and strengthened him with the holy spirit. And had Allah willed those after them would not have fought one with another after clear proofs that had come to them, but they disagreed. So among them were some who believed and among them were others who did not believe. And had Allah willed they would not have fought one with another, but Allah does what He intends. (R 33)
