﴿ أَفَمَن زُيِّنَ لَهُۥ سُوٓءُ عَمَلِهِۦ فَرَءَاهُ حَسَنًۭا ۖ فَإِنَّ ٱللَّهَ يُضِلُّ مَن يَشَآءُ وَيَهْدِى مَن يَشَآءُ ۖ فَلَا تَذْهَبْ نَفْسُكَ عَلَيْهِمْ حَسَرَٰتٍ ۚ إِنَّ ٱللَّهَ عَلِيمٌۢ بِمَا يَصْنَعُونَ ﴾

“Is, then, he to whom the evil of his own doings is [so] alluring that [in the end] he regards it as good [anything but a follower of Satan]? For, verily, God lets go astray him that wills [to go astray], just as He guides him that wills [to be guided]. Hence, [O believer,] do not waste thyself in sorrowing over them: verily, God has full knowledge of all that they do!”

Imam al-Baghawi has reported on the authority of Sayyidna ` Abdullah Ibn ` Abbas ؓ that the verse: فَإِنَّ اللَّـهَ يُضِلُّ مَن يَشَاءُ وَيَهْدِي مَن يَشَاءُ (The fact, therefore, is that Allah lets go astray whomsoever He wills , and leads to the right path whomsoever He wills.- 8) was revealed at a time when the Holy Prophet ﷺ had made the prayer: '0 Allah, bless Islam with prestige and power, through ` Umar Ibn al-Khattab, or Abu Jahl.' Out of the two, Allah Ta’ ala showed the right path to Sayyidna 'Umar ؓ and made him the cause of Islam's prestige and power, while Abu Jahl remained as astray as he was. (Mazhari)
