The enduring good deeds.
His counsel, peace and blessings of Allah be upon him, to Mu'adh Ibn Jabal.
On the authority of Mu'adh Ibn Jabal, may Allah be pleased with him,
that the Messenger of Allah, peace and blessings of Allah be upon him, took him by the hand and said:
"O Mu'adh, by Allah, I truly love you."
Then he said:
"I counsel you, O Mu'adh, never fail to say at the end of every prayer:
'O Allah, help me remember You, thank You, and worship You in the best manner.'"
