إِنَّ اللَّهَ تَعَالَى جَمِيلٌ، يُحِبُّ الْجَمَالَ
Translation: Allah Most High is beautiful and loves beauty.
Source: مسلم
جَمِيلٌ means beautiful and الْجَمَالَ beauty. Allah’s beauty is affirmed in a manner befitting His majesty; it is not compared with the bodily qualities of created beings. For a person, the lesson encourages cleanliness, tidy dress, gracious conduct, and freedom from arrogance. Outward appearance and inward character should not be separated.
إِنَّ adds emphasis. اللَّهَ is its accusative noun and جَمِيلٌ its nominative predicate. يُحِبُّ is a present-tense verb, “He loves,” and الْجَمَالَ is its direct object.
Dressing well can be good, but looking down on others would contradict the lesson’s moral direction.
