Al-Isra' - 17:108

وَيَقُولُونَ سُبْحَانَ رَبِّنَا إِن كَانَ وَعْدُ رَبِّنَا لَمَفْعُولاً
[17:108]
And they say: Glory be to our Lord! most surely the promise of our Lord was to be fulfilled.
"And they say: 'Glory to our Lord! Truly has the promise of our Lord been fulfilled!'"
Saying: Glory to our Lord! Verily the promise of our Lord must be fulfilled.
