They are purchasing miserable prices for Lord Allah’s verses, and thus they are obstructing people from His Path; indeed, how evil they were doing!
‘Lord’s Path’ is Adhikr. Hypocritical transgressors are hiding, rejecting and obstructing mankind from Adhikr—the Best Interpretation of Lord’s Book as mentioned in verse 25: 33. These soulless wrongdoers are distorting Lord’s verses for their whims and for maintaining the organizational spirits. So, they and their disbelieving audience will be gathered in Hell as explained in verse 4: 140. They are filling Fire in their bellies by hiding and purchasing Lord’s verses for a petty price as explained in verse 2: 174.
Without being a believer with Adhikr, prayers will not be responded and deeds will not be accepted as explained in verse 2: 186. They will get Hell as fine for living aimlessly and heedlessly in the 4th phase as explained in verses 2: 39; 7: 179; 9: 67-68; 25: 34 and 65-66. Verse 63: 2 also ends as: “Indeed, how evil they were doing!”. See explanations 2: 159-161; 3: 187 and 6: 26.
