“Yaqoob (PBH) or Israel the grandson of Ibrahim (PBH) had made his sons i.e. the Bani Israel to commit to him before his death that they would serve only one God, the God of their forefathers Ibrahim, Ismael and Ishaq (PBT) and that they would be Muslims. These Prophets were the forefathers of the Bani Israel addressed in the Quran, when they had served only one God and were Muslims then why was it that the Bani Israel who lived during the period of Prophet Muhammed (PBH) did not accept Islam. For those Prophets, would be the reward for what they earned and for the later generation what they earned and they will not be questioned about the deeds of their forefathers, they will be questioned only about their own deeds. ”
