﴿قُلْ إِنْ كَانَ لِلرَّحْمَٰنِ وَلَدٌ فَأَنَا أَوَّلُ الْعَابِدِينَ﴾
81. Say (O Muhammad صلى الله عليه و سلم): "If the Most Gracious (Allâh) had a son (or children as you pretend), then I am the first of Allâh’s worshippers [who deny and refute this claim of yours (and the first to believe in Allâh Alone and testify that He has no children)]. " [Tafsir At-Tabarî].
