Surah Ali 'Imran — Ayah 126 (3:126)
وَمَا جَعَلَهُ ٱللَّهُ إِلَّا بُشۡرَىٰ لَكُمۡ وَلِتَطۡمَئِنَّ قُلُوبُكُم بِهِۦۗ وَمَا ٱلنَّصۡرُ إِلَّا مِنۡ عِندِ ٱللَّهِ ٱلۡعَزِيزِ ٱلۡحَكِيمِ ١٢٦
English translation (Saheeh International)
And Allāh made it not except as [a sign of] good tidings for you and to reassure your hearts thereby. And victory is not except from Allāh, the Exalted in Might, the Wise -
Brief commentary
Allah did not tell you of this reinforcement with angels, except as news to please and reassure your hearts. For in fact, victory does not just come through material means, but comes only from Allah the Mighty, Who no one has any authority over, Wise in His decree and sacred laws.
