Ash-Shuraa 42:14 وما تفرقوا الا من بعد ما جاءهم العلم بغيا بينهم ولولا كلمة سبقت من ربك الى اجل مسمى لقضي بينهم وان الذين اورثوا الكتاب من بعدهم لفي شك منه مريب ١٤

And they were not divided, in jealousy with each other, but after the knowledge had come to them. Had it not been for a word that had come forth earlier from your Lord (and was effective) until a specified time, the matter would have been decided between them. And those who were made to inherit the Book after them are in confounding doubt about it.
