﴿ قُلْ إِنِّىٓ أَخَافُ إِنْ عَصَيْتُ رَبِّى عَذَابَ يَوْمٍ عَظِيمٍۢ ﴾
“Say: "Behold, I would dread, were I [thus] to rebel against my Sustainer, the suffering [which would befall me] on that awesome Day [of Judgment]."”
(Say) O Muhammad: (I fear) I know, (if I rebel against my Lord) and worship other than Him, I would be reverting back to your religion, (the retribution of an Awful Day) I would face then a tremendous torment on an Awful Day; it is also said that this means: I would be facing torment on an Awful Day.
