(The Importance of Religious Education)
When the believers mobilize, not all of them shall do so. A few from each group shall mobilize by devoting their time to studying the religion. Thus, they can pass the knowledge on to their people when they return, that they may remain religiously informed.
وَما كانَ المُؤمِنونَ لِيَنفِروا كافَّةً فَلَولا نَفَرَ مِن كُلِّ فِرقَةٍ مِنهُم طائِفَةٌ لِيَتَفَقَّهوا فِى الدّينِ وَلِيُنذِروا قَومَهُم إِذا رَجَعوا إِلَيهِم لَعَلَّهُم يَحذَرونَ
