(At-twur) 52 : 40
أَمْ تَسْأَلُهُمْ أَجْرًا فَهُمْ مِنْ مَغْرَمٍ مُثْقَلُونَ

Or do they ask any reward, thus are they overburdened by debt?

The Messengers and believers neither impose Lord’s Book Adhikr upon anyone compulsorily and making burden to him, nor accept any reward from the mankind for conveying It. Whoever accepts any type of reward for conveying or teaching Lord’s Book, such are the disbelievers who prefer this worldly life than the Hereafter. From such transgressing Hypocrites who are filing their bellies with fire as explained in verses 2: 174-175, no one will get Guidance. They neither utilise Adhikr themselves, nor give It to others for utilising as explained in verse 6: 26. Thus they are hastening for the destruction of the universe. See explanation 7: 156-157; 33: 60-61; and 38: 86-87.
