42:14
وَمَا تَفَرَّقُوٓا۟ إِلَّا مِنۢ بَعْدِ مَا جَآءَهُمُ ٱلْعِلْمُ بَغْيًۢا بَيْنَهُمْ ۚ وَلَوْلَا كَلِمَةٌۭ سَبَقَتْ مِن رَّبِّكَ إِلَىٰٓ أَجَلٍۢ مُّسَمًّۭى لَّقُضِىَ بَيْنَهُمْ ۚ وَإِنَّ ٱلَّذِينَ أُورِثُوا۟ ٱلْكِتَٰبَ مِنۢ بَعْدِهِمْ لَفِى شَكٍّۢ مِّنْهُ مُرِيبٍۢ
And they did not become divided until after knowledge had come to them - out of jealous animosity between themselves. And if not for a word that preceded from your Lord [postponing the penalty] until a specified time, it would have been concluded between them. And indeed, those who were granted inheritance of the Scripture after them are, concerning it, in disquieting doubt.

Tafsir
Ibn Kathīr (abridged)
The Religion of the Messengers is One
Allah says to this Ummah:
شَرَعَ لَكُم مِّنَ الِدِينِ مَا وَصَّى بِهِ نُوحاً وَالَّذِى أَوْحَيْنَآ إِلَيْكَ
(He (Allah) has ordained for you the same religion which He ordained for Nuh, and that which We have revealed to you,) Allah mentions the first Messenger who was sent after Adam, that is, Nuh, peace be upon them, and the last of them is Muhammad . Then He mentions those who came in between them who were the Messengers of strong will, namely Ibrahim, Musa and `Isa bin Maryam. This Ayah mentions all five, just as they are also mentioned in the Ayah in Surat Al-Ahzab, where Allah says:
وَإِذْ أَخَذْنَا مِنَ النَّبِيِّيْنَ مِيثَاقَهُمْ وَمِنْكَ وَمِن نُّوحٍ وَإِبْرَهِيمَ وَمُوسَى وَعِيسَى ابْنِ مَرْيَمَ
(And (remember) when We took from the Prophets their covenant, and from you, and from Nuh, Ibrahim, Musa, and `Isa son of Maryam.) (33:7). The Message which all the Messengers brought was to worship Allah Alone, with no partner or associate, as Allah says:
