Just like that, We awakened them, so that they might ask one another. One of them asked: “How long have you remained?" They said, "We have remained a day or part of a day". They said: "Your Lord is most knowing of how long you remained. So send one of you with this silver coin of yours to the city and let him look to which is the best of food and bring you provision from it and let him be cautious, and let no one be aware of you.
When they woke up, they sent one among them for getting Food. Being believers, they were looking for food that is wholesome and permissible. Adhikr is the Food, Cloth, and Sight of the human soul as explained in verse 7: 26. So the believer who testifies Adhikr will select wholesome and permissible food as explained in verse 16: 114. It is told in verses 56: 77-79 that, those who eat wholesome and permissible food can only grasp the Noble Reading Adhikr.
The Arabic Quran reading hypocrites who hide Adhikr are commanding evil and are forbidding good to their Mushrik followers. By purchasing petty price for Lord’s verses, they are filling Fire in their bellies as explained in verses 2: 174-175. For the Fujjar, Adhikr is filthy, so Adhikr will increase filth over filth for them as explained in verses 9: 28, 95, and 125. Whatever earned by following Satanic footsteps is not wholesome and permissible as explained in verses 2: 168-169. See explanation 4: 29; 7: 169-170 and 10: 27.
