Surah At-Tawbah — Ayah 26 (9:26)
ثُمَّ أَنزَلَ ٱللَّهُ سَكِينَتَهُۥ عَلَىٰ رَسُولِهِۦ وَعَلَى ٱلۡمُؤۡمِنِينَ وَأَنزَلَ جُنُودٗا لَّمۡ تَرَوۡهَا وَعَذَّبَ ٱلَّذِينَ كَفَرُواْۚ وَذَٰلِكَ جَزَآءُ ٱلۡكَٰفِرِينَ ٢٦
English translation (Saheeh International)
Then Allāh sent down His tranquility upon His Messenger and upon the believers and sent down soldiers [i.e., angels] whom you did not see and punished those who disbelieved. And that is the recompense of the disbelievers.
Brief commentary
Then, after they ran away from their enemy, Allah sent down calm upon His Messenger and the believers, so that they became patient in fighting; and He sent angels they could not see, and punished the disbelievers with death, capture and seizure of their wealth, women and children. These disbelievers were repaid in this way for their rejection of the Messenger.
