And these (rejecters of the faith) split themselves into factions only after (true) knowledge (of the fundamental principles of faith) had come to them (and that too) out of jealousy among themselves and to spite one another. But for the word (of promise) already gone forth from your Lord, (that they would be given respite) for a fixed term, the judgment upon these (disbelievers) would surely have long been passed (by their complete annihilation). As for those who have been made to inherit the Scripture after these (Prophets) they are in a disquieting and grave doubt about this (Qur'ân).
