Abu Huraira reported Allah's Messenger (ﷺ) as saying: Two are the expressions which are light on the tongue, but heavy in scale, dear to the Compassionate One:" Exalted is Allah (He is free from imperfection) and all praise is due to Him" ;" Exalted is Allah (He is free from imperfection), the Great."
