اللَّهُ أَحَدٌ ... وَلَمْ يَكُنْ لَهُ كُفُوًا أَحَدٌ
Allah is uniquely One ... and none is His equal. (112:1, 4)
Aḥad occurs near the opening and at the close, but not in identical roles. Initially it positively affirms unique oneness; at the end, within a negated kāna construction, it helps deny any possible equal.
Affirmation and denial complement one another. Merely calling this an echo would be incomplete: the second occurrence protects the positive claim by excluding its rival possibility.
