Salaam Alaikum,
Mu’adh (RA) reported: The Messenger of Allah (peace be upon him) took hold of my hand and said, “O Mu’adh! By Allah I love you, so I advise you to never forget to recite after every prayer:
“Allâhumma a’innî alâ dhikrika, wa shukrika, wa husni ‘ibâdatika
O Allah, help me remember You, to be grateful to You, and to worship You in an excellent manner”
[Abu Dawud] [Book 16, Hadith 1422]
This dua should be recited after every salah.
Peace.
