الْأَسْقَعُ الْبَكْرِيُّ
The Prophet ﷺ came to them in the swelling place of immigrants and a man asked him: Which is the greatest verse of the Qur'an ? The Prophet ﷺ replied: Allah, there is no god but He - the Living, the Self-Subsisting Eternal. No slumber can seize Him nor sleep." (Using translation from Abū Dāʾūd 4003)
أَنَّ النَّبِيَّ ﷺ جَاءَهُمْ فِي صِفَةِ الْمُهَاجِرِينَ فَسَأَلَهُ إِنْسَانٌ أَيُّ آيَةٍ فِي الْقُرْآنِ أَعْظَمُ؟ فَقَالَ النَّبِيُّ ﷺ {اللهُ لَا إِلَهَ إِلَّا هُوَ الْحَيُّ الْقَيُّومُ لَا تَأْخُذُهُ سِنَةٌ وَلَا نَوْمٌ}
