اللَّهُمَّ أَعِنِّي عَلَى ذِكْرِكَ وَشُكْرِكَ وَحُسْنِ عِبَادَتِكَ
Allahumma a'inni 'ala dhikrika wa shukrika wa husni 'ibadatik
O Allah, help me to remember You, to thank You, and to worship You in the best manner.
The Prophet ﷺ took Mu'adh ibn Jabal (RA) by the hand and said: "O Mu'adh, by Allah I love you." Then he said: "I advise you, O Mu'adh: never leave saying this after every prayer." This shows how important this du'a is — the Prophet ﷺ personally advised one of his most beloved Companions with it.
