(55) باب فَضْلِ الْحَامِدِينَ
It was narrated that 'Aishah said:
"When the Messenger of Allah (ﷺ) saw something he liked, he would say: 'Al-hamdu lillahil-ladhi bi ni'matihi tatimmus-salihat (Praise is to Allah by Whose grace good deeds are completed).' And if he saw something that he disliked, he would say: 'Al-hamdu lillahi 'ala kulli hal (Praise is to Allah in all circumstances).'"
