Mu’adh (رضي الله عنه) reported: The Messenger of Allah (صلى الله عليه وسلم) 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:
اللَّهُمَّ أَعِنِّي عَلَى ذِكْرِكَ، وَشُكْرِكَ، وَحُسْنِ عِبَادَتِكَ
“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 Hadith 1522, Nasa’i Hadith 1303 and Al-Adab Al-Mufrad 690]
