Surah Ash-Shu'ara — Ayah 67 (26:67)
إِنَّ فِي ذَٰلِكَ لَأٓيَةٗۖ وَمَا كَانَ أَكۡثَرُهُم مُّؤۡمِنِينَ ٦٧
English translation (Saheeh International)
Indeed in that is a sign, but most of them were not to be believers.
Brief commentary
Indeed, in the parting of the sea for Moses, his salvation from Pharaoh and Pharaoh’s destruction, is a miracle proving the truthfulness of Moses. The majority of those with Pharaoh were not believers, they were rejecters.
