﴿ خَتَمَ ٱللَّهُ عَلَىٰ قُلُوبِهِمْ وَعَلَىٰ سَمْعِهِمْ ۖ وَعَلَىٰٓ أَبْصَٰرِهِمْ غِشَٰوَةٌۭ ۖ وَلَهُمْ عَذَابٌ عَظِيمٌۭ ﴾

“God; has sealed their hearts and their hearing, and over their eyes is a veil; and awesome suffering awaits them.”

(Allah hath sealed their hearts), stamped their hearts, (and their hearing, and on their eyes there is a covering), on their eyes there is a shield (and theirs will be an awful doom) an awful torment in the Hereafter. This refers in particular to the Jews Ka'b Ibn al-Ashraf, Huyayy Ibn Akhtab and Judayy Ibn Akhtab. It is also said that it refers to the idolaters of Mecca 'Utbah [Ibn Rabi'ah], Shaybah [Ibn Rabi'ah] and al-Walid [Ibn al-Mughirah].
