"Allah's Greatest Names is in these two verses: "And your Ilaah (God) is One Ilaah (God), none has the right to be worshipped but He, the Ever-Merciful, the Mercy-Giving' and the beginning of Surah Al 'Imran, "A.L.M Allah, there is no deity but He, the Living, the Eternal."

أَنَّ النَّبِيَّ ﷺ قَالَ اسْمُ اللَّهِ الأَعْظَمُ فِي هَاتَيْنِ الآيَتَيْنِ { وَإِلَهُكُمْ إِلَهٌ وَاحِدٌ لاَ إِلَهَ إِلاَّ هُوَ الرَّحْمَنُ الرَّحِيمُ } وَفَاتِحَةُ سُورَةِ آلِ عِمْرَانَ { الم * اللَّهُ لاَ إِلَهَ إِلاَّ هُوَ الْحَىُّ الْقَيُّومُ }
