(Al-Qalam) 68 : 46
أَمْ تَسْأَلُهُمْ أَجْرًا فَهُمْ مِنْ مَغْرَمٍ مُثْقَلُونَ

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

As explained in verses 7: 156-158, Messenger Muhammed is deputed to entire mankind with Adhikr-the Light-in order to enable them to unload all life burdens and to free them from all types of shackles which had been tied upon them and to eradicate the injustice that existed there, and to unload all liabilities covered them, and thus to go to the Paradise peacefully which is prepared from this world. See explanation 25: 57; 36: 7-9; and 52: 40.
