﴿ لَّوْلَآ أَن تَدَٰرَكَهُۥ نِعْمَةٌۭ مِّن رَّبِّهِۦ لَنُبِذَ بِٱلْعَرَآءِ وَهُوَ مَذْمُومٌۭ ﴾

“[And remember:] had not grace from his Sustainer reached him, he would indeed have been cast forth upon that barren shore in a state of disgrace:”

Had it not been for a grace a mercy from his Lord that reached him he would have surely been cast out of the belly of the whale onto a wilderness a desolate land while he was blameworthy — but he was shown mercy and was therefore cast out blameless.
