[2:174] Those who conceal what God has revealed of the Scripture, and sell it for a little price - they shall consume nothing in their bellies but the Fire; God shall not speak to them on the Day of Resurrection, neither purify them; and theirs is a painful chastisement.
The religious scholars (ʿulamāÌ) seek the spread of the evidentiary proofs of knowledge while the friends (awliyāÌ) are commanded to preserve the trusts of the secret. If [the scholars] conceal the proofs of different types of knowledge, they will be bridled with a bridle of fire. On the other hand, if [the friends] divulge even a sliver from the secret, they are immediately distanced from the secrets and snatched away from what they have been given in lights. To each is a limit (ḥadd) and to each a command (amr).
