Surah Al-Isra — Ayah 108 (17:108)
وَيَقُولُونَ سُبۡحَٰنَ رَبِّنَآ إِن كَانَ وَعۡدُ رَبِّنَا لَمَفۡعُولٗا ١٠٨
English translation (Saheeh International)
And they say, "Exalted is our Lord! Indeed, the promise of our Lord has been fulfilled."
Brief commentary
And they say in their prostration: Our Lord will never break His promise. The promise He made of sending Muhammad (peace be upon him) is going to happen. Surely, our Lord’s promise of this and other matters will definitely occur.
