said:
The Prophet ﷺ met me and said:
«O Mu’aadh, indeed I love you for the Sake of Allaah.»[And] I replied: ‘And I swear by Allaah O Messenger of Allaah, I [too] love you for the Sake of Allaah.’ He ﷺ then said:
«Shall I teach you [some] words which you can recite after every prayer? [And they are]:
رَبِّ أَعِنِّي عَلَى ذِكْرِكَ وَ شُكْرِكَ وَ حُسْنِ عِبَادَتِكَ
O my Lord! Aid me in Your remembrance, and Your gratitude and the perfection of Your worship.»
