Sc., "of what is good and what is bad for them". - For an explanation of God's "sealing" the hearts of those who are bent on denying the truth, see 2:7 and the corresponding note.
Cf. ii. 7. On account of their iniquities and their want of Faith their hearts and their senses become impervious to Allah's grace, and they run headlong to perdition.
