The Prophet ﷺ said, "There are two expressions which are very easy for the tongue to say, but they are very heavy in the balance and are very dear to The Beneficent (Allah), and they are, 'Subhan Allah Al- ʿAzim and 'Subhan Allah wa bihamdihi.'" (Using translation from Bukhārī 6406)   

قَالَ رَسُولُ اللهِ ﷺ كَلِمَتَانِ خَفِيفَتَانِ عَلَى اللِّسَانِ ثَقِيلَتَانِ فِي الْمِيزَانِ حَبِيبَتَانِ إِلَى الرَّحْمَنِ سُبْحَانَ اللهِ وَبِحَمْدِهِ سُبْحَانَ اللهِ الْعَظِيمِ [306] 10598 وَعَنْ عَلِيِّ بْنِ الْمُنْذِرِ عَنْ مُحَمَّدِ بْنِ فُضَيْلٍ بِهِ
