Mu’adh ibn Jabal reported: The Messenger of Allah took me by the hand and he said, O Mu’adh, I swear by Allah that I love you. I swear by Allah that I love you. O Mu’adh, I advise you not to forget supplicating after every prayer by saying: O Allah, help me to remember you, to give thanks to you, and to worship you in the best manner. [Abi Dawud]
