These apostles : We have preferred some of them above some others : of them are some unto whom Allah spake , and some He raised many degrees . And We vouchsafed unto Isa , son of Maryam , the evidences , and We aided him with the holy spirit ; and had Allah so willed those who came after them had not fought among themselves after the evidences had come unto them but they differed ; then of them some believed and of them some disbelieved .
