وَلَا تَكُونُوا۟ كَٱلَّذِينَ تَفَرَّقُوا۟ وَٱخْتَلَفُوا۟ مِنۢ بَعْدِ مَا جَآءَهُمُ ٱلْبَيِّنَٰتُ ۚ وَأُو۟لَٰٓئِكَ لَهُمْ عَذَابٌ عَظِيمٌ
3:104; 6:160; 8:47.
Commentary:
The Quran does not merely give general philosophic teachings but actually refers to historical facts to bring home to the Faithful the gravity of the dangers that proved the ruin of peoples gone by. The verse, therefore, aptly refers to the dissensions of the People of the Book, and Muslims are enjoined to avoid them. The Holy Prophet says: "Whoso separates himself from the body of the Muslims even by the space of a span, throws off from his neck the rope of Muslim brotherhood (Dawud). Again, "whoso severs his connection (with the community of the Muslims) will be cast into the Fire" (Tirmidhi, ch. on Fitan).
