لَّقَدْ جِئْتُمْ شَيْـًٔا إِدًّا
Important Words:
اداً (most hideous) is derived from أد. They say أدہ الویل i.e. a terrible calamity befell him. أدہ الامر means, the event or affair oppressed him, distressed him or afflicted him. امرإد means, a very evil, abominable, severe, thing or affair; an evil thing against which human nature revolts or which causes an uproar on account of its extreme abomination (Lane & Aqrab).
Commentary:
The verse purports to say that شرک (idolatry) is a most abominable thing. Human nature revolts against it and reason and intellect recoil in disgust from it and no sane person can help protesting against such a blasphemous practice or belief. No doctrine has been condemned so strongly and repeatedly in the Quran as the Christian dogma that Jesus, son of Mary, a mortal, subject to all human weaknesses and frailties, was the son of God.
