The people of Dhikr (memory and knowledge) that Allah has commanded the creatures to ask for their questions are the Imams عليه السلام

9. Ahmad ibn Muhammad has narrated from Ahmad ibn Muhammad ibn abu Nasr who has said that he wrote a letter to Imam al-Rida عليه السلام. Of the issues for which he requested explanation in the letter one was about the following words of Allah, Most Holy, the Most High. “Ask the people of Dhikr (people who remind of Allah) if you do not know.” The other question was about the words of Allah, the Most Holy, the Most High, “Not all believers have to become specialists in religious learning. Why do not some people from each group of believers seek to become specialists in religious learning and, after completing their studies, guide their group so that they will have fear of God.” (9:122) thus, it is obligatory for them to ask but it is not obligatory for you to answer.” The Imams عليه السلام has said the following for the answer. “If they would not do what you would ask them, know that they are only following their (evil) desires. Who strays more than one who follows his desires without guidance from God? . .” (28:50)
