122 Preface ۞ وَما كانَ المُؤمِنونَ لِيَنفِروا كافَّةً ۚ فَلَولا نَفَرَ مِن كُلِّ فِرقَةٍ مِنهُم طائِفَةٌ لِيَتَفَقَّهوا فِي الدّينِ وَلِيُنذِروا قَومَهُم إِذا رَجَعوا إِلَيهِم لَعَلَّهُم يَحذَرونَAli Quli QaraiYet it is not for the faithful to go forth en masse.1 But why should not there go forth a group from each of their sections to become learned in religion, and to warn their people when they return to them, so that they may beware? That is, it is not feasible, or reasonable, for all the faithful to set out for Madīnah, the Prophet’s city, for the study of the religious sciences.
