وَوَعْدَهُ وَوَعِيدَهُ
And His promises and warnings.
A promise here announces reward and good outcomes for obedience, while a warning alerts people to the consequences of disobedience. These are not only motivational expressions; they concern accountability and the Hereafter.
Commands and prohibitions establish what ought to be done or avoided. Promises and warnings explain the significance and consequences of compliance or transgression. Thus divine guidance connects obligations with outcomes.
