Supplication: “O Allah, help me to remember You, give thanks to You, and worship You in the best manner,” and its place

Question:
Honorable Shaykh, may Allah grant you success, the author says, “and he supplicates with what has been transmitted.” Does this include supplicating by saying, “O Allah, help me to remember You, give thanks to You, and worship You in the best manner”?

Answer:
Yes, this has been transmitted. The scholars differed on whether this is said at the end of the prayer or after the prayer. There are two opinions: some said it is said at the end of the prayer, and others said it is said after the prayer, because the Prophet (peace and blessings be upon him) said to Mu’adh, “O Mu’adh, I love you,” so . They differed in interpreting “after the prayer” (dabr al-salah): does it mean the end of the prayer, or does it mean after the prayer?
That is, because both meanings are possible. So the one who said it means the end of the prayer said he supplicates with it before the prayer [ends], and the one who said it means after the prayer said he supplicates with it after the prayer. The matter is possible [in both senses]. If he does it in the prayer, there is no harm, and if he does it after the prayer, there is no harm, because it is possible [in both senses].
