TIRMIDHI 2884:
from al-Ḥumaydī —
"Allah has not created in the heavens nor in the earth what is more magnificent than Ayat Al-Kursi." Sufyan said: "Because Ayat Al-Kursi is the Speech of Allah, and Allah's Speech is greater than Allah's creation of the heavens and the earth."
الترمذي ٢٨٨٤:
عن الحميدي —
مَا خَلَقَ اللَّهُ مِنْ سَمَاءٍ وَلاَ أَرْضٍ أَعْظَمَ مِنْ آيَةِ الْكُرْسِيِّ قَالَ سُفْيَانُ لأَنَّ آيَةَ الْكُرْسِيِّ هُوَ كَلاَمُ اللَّهِ وَكَلاَمُ اللَّهِ أَعْظَمُ مِنْ خَلْقِ اللَّهِ مِنَ السَّمَاءِ وَالأَرْضِ
