حَدَّثَنَا مُحَمَّدُ بْنُ إِسْمَاعِيلَ، قَالَ حَدَّثَنَا الْحُمَيْدِيُّ، حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، فِي تَفْسِيرِ حَدِيثِ عَبْدِ اللَّهِ بْنِ مَسْعُودٍ قَالَ 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 ‏.‏

Narrated 'Abdullah bin Mas'ud: "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." Translation Not Available
