Of all these Messengers (whom We sent) We have exalted some above others: Allah spoke to some of them (directly), and raised some (above all others) in rank (i.e. elevated the Holy Prophet [Allah bless him and give him peace] to the highest of all the degrees of the glory of Messengership). And We gave ‘Isa son of Maryam (Jesus son of Mary), clear Signs and helped him with the Holy Spirit. And had Allah so willed, the people succeeding these Messengers would never have disputed and fought among themselves, after the manifest Signs had come to them. But they differed (owing to the free will which was endowed to them to be answerable before Allah for their performance). So, some of them believed while others opted to disbelieve. (And keep it in mind that) if Allah had willed (i.e. restricted their choice to one opinion only) they would never have fought among themselves. But Allah does what He desires.
