The people used to be one community when GOD sent the prophets as bearers of good news, as well as warners. He sent down with them the scripture, bearing the truth, to judge among the people in their disputes. Ironically, those who received the scripture were the ones who rejected any new scripture, despite clear proofs given to them. This is due to jealousy on their part. GOD guides those who believe to the truth that is disputed by all others, in accordance with His will. GOD guides whoever wills in a straight path.
