8لِيَسأَلَ الصّادِقينَ عَن صِدقِهِم ۚ وَأَعَدَّ لِلكافِرينَ عَذابًا أَليمًا(Saheeh International)That He may question the truthful about their truth.1 And He has prepared for the disbelievers a painful punishment. i.e., that He may ask the prophets what they conveyed to their people and what response they received. "The truthful" may also refer to those who believed in the message conveyed by the prophets and imparted it to others.
