Hadith, Dua and status: Prayer to remember, thank and worship Allah in best and excellent manner

Mu’ādh ibn Jabal narrated the Messenger of Allāh صَلَّى اللّٰهُ عَلَيْهِ وَسَلَّمَ took his hand and said: “O’ Mu’ādh, by Allāh I love you.” Then he said: “I advise you, O’ Mu’ādh, do not fail to say upon completing every prayer: 

*اللَّهُمَّ أَعِنِّي عَلَى ذِكْرِكَ، وَشُكْرِكَ، وَحُسْنِ عِبَادَتِكٙ*

‘O’ Allāh, help me to remember You, to be grateful to You, and to worship You in an excellent manner.’”
