9:122 [QXP]The believers shall not all go to an expedition. Of every group of believers, let some of them come forth to gain sound knowledge of DEEN (the Qur'anic System of life). Then they can pass the knowledge on to their people when they return, so that they may remain aware.
Question: Does this suggests that there be a group of "scholars" among Muslims to teach Deen?
In case of a "Yes" my follow up question would be in this day and age of scholars with differences of opinion (even with Qur'an interpretation - never mind others) how are we to pick the best one?
