Surah Al-Anfal, ayah 57

8:57

فَإِمَّا تَثۡقَفَنَّهُمۡ فِي ٱلۡحَرۡبِ فَشَرِّدۡ بِهِم مَّنۡ خَلۡفَهُمۡ لَعَلَّهُمۡ يَذَّكَّرُونَ ٥٧

Fa immā tathqafannahum fil-harbi fasharrid bihim man khalfahum la'allahum yaddhakkarūn

So if you, [O Muḥammad], gain dominance over them in war, disperse by [means of] them those behind them that perhaps they will be reminded.454
