Surah Ar-Rum (The Romans), Verse 6

وَعْدَ اللّٰهِ لَا یُخْلِفُ اللّٰهُ وَعْدَهٗ وَلٰكِنَّ اَكْثَرَ النَّاسِ لَا یَعْلَمُوْنَ ۟

Wa'dal laahi laa yukhliful laahu wa'dahoo wa laakin na aksaran naasi laa ya'lamoon

“(It is) the promise of Allah. Never does Allah depart from His promise: but most men understand not.”

Quran 30:6 (Yusuf Ali Translation)
