Say (O Muhammad SAW): "If the Most Beneficent (Allah) had a son (or children as you pretend), then I am the first of Allah's worshippers [who deny and refute this claim of yours (and the first to believe in Allah Alone and testify that He has no children)]." [Tafsir At-Tabari].
Ka ce: "Idan har akwai ɗã ga Mai rahama, to, nĩ ne farkon mãsu bauta (wa ɗan)."
