ALL MANKIND were once one single community; [then they began to differ -] whereupon God raised up the prophets as heralds of glad tidings and as warners, and through them bestowed revelation from on high, setting forth the truth, so that it might decide between people with regard to all on which they had come to hold divergent views. Yet none other than the selfsame people who had been granted this [revelation] began, out of mutual jealousy, to disagree about its meaning after all evidence of the truth had come unto them. But God guided the believers unto the truth about which, by His leave, they had disagreed: for God guides onto a straight way him that wills [to be guided].
