اقرأ وتدبر الآية 4286 من سورة سُورَةُ الشُّورَىٰ: وَمَا تَفَرَّقُوا إِلَّا مِنْ بَعْدِ مَا جَاءَهُمُ الْعِلْمُ بَغْيًا بَيْنَهُمْ ۚ وَلَوْلَا كَلِمَةٌ سَبَقَتْ مِنْ رَبِّكَ إِلَىٰ أَجَلٍ مُسَمًّى لَقُضِيَ بَيْنَهُمْ ۚ وَإِنَّ الَّذِينَ أُورِثُوا الْكِتَابَ مِنْ بَعْدِهِمْ لَفِي شَكٍّ مِنْهُ مُرِيبٍ
وَمَا تَفَرَّقُوا إِلَّا مِنْ بَعْدِ مَا جَاءَهُمُ الْعِلْمُ بَغْيًا بَيْنَهُمْ ۚ وَلَوْلَا كَلِمَةٌ سَبَقَتْ مِنْ رَبِّكَ إِلَىٰ أَجَلٍ مُسَمًّى لَقُضِيَ بَيْنَهُمْ ۚ وَإِنَّ الَّذِينَ أُورِثُوا الْكِتَابَ مِنْ بَعْدِهِمْ لَفِي شَكٍّ مِنْهُ مُرِيبٍ
And [as for the followers of earlier revelation,] they broke up their unity, out of mutual jealousy, only after they had come to know [the truth]. And had it not been for a decree that had already gone forth from thy Sustainer, [postponing all decision] until a term set [by Him], all would indeed have been decided between them [from the outset]. As it is, behold, they who have inherited their divine writ from those who preceded them are [now] in grave doubt, amounting to suspicion, about what it portends.
