Sunan Ibn Majah Book 33, Hadith 148
the Prophet (ﷺ) used to say: "Al-hamdu lillahi 'ala kulli hal. Rabbi a'udhu bika min hali ahlin-nar (Praise is to Allah in all circumstances, O Allah, I seek refuge with You from the situation of the people of Hell)."
"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).'"
the Messenger of Allah (ﷺ) said: 'Allah does not bestow a blessing upon any slave and he says: 'Al-hamdu Lillah (praise is to Allah),' except that what he gives (the praise) is better than what he received (the blessing)."
