To differ after being given knowledge means that, even after receiving the call for Truth, man ignores it or opposes it. Through the Prophet Muhammad, God Almighty revealed religion (din) in its pure form. This meant that all those who were desirous of God should have joined it. But, they were not prepared to join the Prophet. By remaining attached to the previous prophets, they enjoyed the position of the pious ones among the people. They thought that this was enough for them, while the fact is that when the call of the True Religion is raised it becomes compulsory on the part of all the people to demolish their biases and prejudices and join the True Religion. Those who do not do so are guilty in the eyes of God, irrespective of their being ostensibly religious. When the call of True religion is given, some people reject it out of jealousy or a false sense of pride (bagh’i), while others stay away from it because of their doubts. This is the case of such people as have attained an elevated status in society. Acceptance of Truth by them would involve stepping down from their high positions. As they are not prepared to lower themselves, they set about belittling the call for Truth in order to justify their stand. The common people are generally beset by doubt and hesitation. The call of the preacher of Truth appears to them weighty on the basis of argument, but at the same time they find it difficult to ignore the great ones whose imagined greatness is already impressed on their minds. This dual pressure becomes a hindrance to their reaching a final decision. The first group ignores the Truth under the influence of a false sense of pride, while the second group does not accept it under the influence of doubt. In effect, both groups thus deprive themselves of the Truth.
