Quran's Tafhim ( explanation)
*136). To make no distinction between the Prophets means not to hold some of them to he right and the others to be wrong, not to recognize some to have been the recipients of Divine revelation and the others not. All the Prophets sent by God invited men to the same Truth and to the same way. Hence for anyone who is really a lover of Truth it is necessary that he should recognize all of them to be its bearers. Those who believe in one particular Prophet and disbelieve in others do not in fact believe even in that particular Prophet in whom they, claim to believe, for they have not grasped the nature of that universal 'Straight Way' (al-sirat al-mustaqim) which was enunciated by Moses, Jesus and the other Prophets. When such people claim to foliow a Prophet they, really mean that they do so out of deference to their forefathers. Their religion in fact consists of bigoted ancestor-worship and blind imitation of inherited customs rather than sincere adherence to the directives of any Prophet of God.
