وَهُوَ الْغَفُورُ الْوَدُودُ
And He is the All-Forgiving, the Most Loving.
In some contexts, a definite predicate highlights the exceptional or complete possession of a quality by a specific subject. The divine attributes in the verse convey the perfection of these qualities.
A restrictive implication comes from the sentence as a whole and its context; an article alone does not mechanically deny every degree of the quality to all other beings.
