9:122
۞ وَمَا كَانَ ٱلۡمُؤۡمِنُونَ لِیَنفِرُوا۟ كَاۤفَّةࣰۚ فَلَوۡلَا نَفَرَ مِن كُلِّ فِرۡقَةࣲ مِّنۡهُمۡ طَاۤىِٕفَةࣱ لِّیَتَفَقَّهُوا۟ فِی ٱلدِّینِ وَلِیُنذِرُوا۟ قَوۡمَهُمۡ إِذَا رَجَعُوۤا۟ إِلَیۡهِمۡ لَعَلَّهُمۡ یَحۡذَرُونَ
And the believers should not all go out to fight. Of every troop of them, a party only should go forth, that they (who are left behind) may gain sound knowledge in religion, and that they may warn their folk when they return to them, so that they may beware.
— Mohammed Marmaduke William Pickthall
