81قُلْ إِن كَانَ لِلرَّحْمَـٰنِ وَلَدٌ فَأَنَا۠ أَوَّلُ ٱلْعَـٰبِدِينَ
82سُبْحَـٰنَ رَبِّ ٱلسَّمَـٰوَٰتِ وَٱلْأَرْضِ رَبِّ ٱلْعَرْشِ عَمَّا يَصِفُونَ
83فَذَرْهُمْ يَخُوضُوا۟ وَيَلْعَبُوا۟ حَتَّىٰ يُلَـٰقُوا۟ يَوْمَهُمُ ٱلَّذِى يُوعَدُونَ

64It means: "My rejection of somebody's being God's offspring and my refusal to worship those whom you regard as His offspring is not due to any stubbornness and obduracy. My reason for the refusal is only this that God has no son or daughter, and your such beliefs are against the reality; otherwise I am such a faithful servant of my Lord that if at all the reality had been the same as you state I would have submitted myself in worship before you.
