and it is not for the believers to march forth all together. so why should not a band from each party of them march forth so that they may gain understanding in religion and that when they come back unto them haply they might warn their people when they come back unto them haply they may beware!
وما كان المؤمنون لينفروا كافة فلولا نفر من كل فرقة منهم طائفة ليتفقهوا في الدين ولينذروا قومهم إذا رجعوا إليهم لعلهم يحذرون
