Then is one to whom the evil of his deed has been made attractive so he considers it good [like one rightly guided]? For indeed, Allāh sends astray whom He wills and guides whom He wills. So do not let yourself perish over them in regret. Indeed, Allāh is Knowing of what they do.
The one for whom the satan has beautified his bad actions and so he thinks them to be good is not like the one for whom Allah has beautified the truth and so he believes it to be the truth, because Allah leads astray whom He wants and guides whom He wants, without anyone to compel Him. So do not destroy yourself, O Messenger, out of grief over the misguidance of the misguided. Allah is Knowing of what they do. Nothing of their actions is hidden from Him.
