it is not right that all the believers should go out all together. why then does not a party from every group come to in order to acquire a deeper knowledge of religion and to warn their people so that they can guard themselves against evil?
وما كان المؤمنون لينفروا كافة فلولا نفر من كل فرقة منهم طائفة ليتفقهوا في الدين ولينذروا قومهم إذا رجعوا إليهم لعلهم يحذرون
