(Al-Muaminoon) 23 : 77
حَتَّىٰ إِذَا فَتَحْنَا عَلَيْهِمْ بَابًا ذَا عَذَابٍ شَدِيدٍ إِذَا هُمْ فِيهِ مُبْلِسُونَ
Until when We open upon them door of severe punishment, immediately they will become despair in it.
The believer will never bow down before anyone except Lord, whereas the worthless Fujjar will bow down to any creatures other than Creator Lord. See explanation 3: 149-151; 6: 44-45 and 22: 18.
