ذَٰلِكُمُ ٱللَّهُ رَبُّكُمْ خَـٰلِقُ كُلِّ شَىْءٍ لَّآ إِلَـٰهَ إِلَّا هُوَ ۖ فَأَنَّىٰ تُؤْفَكُونَ Qur’an Ghafir (40:62)Thalikumu Allahu rabbukum khaliqu kulli shayin la ilaha illa huwa faanna tufakoona
Sc., "O you who deny this truth!" For my above rendering of tu'fakun, see note [90] on the last sentence of 5:75 .
If we worship false gods, i.e., go after vanities, what is it that deludes us and leads us astray? What could it be but our rank ingratitude and failure to use the understanding which Allah has given us?
