سورة Az-Zukhruf ( The Gold Adornment ) - الآية 81

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].
