The Prophet ﷺ said, "(There are) two words which are dear to the Beneficent (Allah) and very light (easy) for the tongue (to say), but very heavy in weight in the balance. They are: ''Subhan Allah wa-bi hamdihi'' and ''Subhan Allah Al-ʿAzim." (see Hadith 6682).
قَالَ النَّبِيُّ ﷺ كَلِمَتَانِ حَبِيبَتَانِ إِلَى الرَّحْمَنِ خَفِيفَتَانِ عَلَى اللِّسَانِ ثَقِيلَتَانِ فِي الْمِيزَانِ سُبْحَانَ اللَّهِ وَبِحَمْدِهِ سُبْحَانَ اللَّهِ الْعَظِيمِ
