Surah Ali 'Imran — Ayah 127 (3:127)
لِيَقۡطَعَ طَرَفٗا مِّنَ ٱلَّذِينَ كَفَرُوٓاْ أَوۡ يَكۡبِتَهُمۡ فَيَنقَلِبُواْ خَآئِبِينَ ١٢٧
English translation (Saheeh International)
That He might cut down a section of the disbelievers or suppress them so that they turn back disappointed.
Brief commentary
Your victory in the Battle of Badr was because Allah willed that a group of the disbelievers be destroyed, and another be humiliated, frustrating them through defeat so that they withdrew.
