Mu'adh ibn Jabal said, "The Prophet, may Allah bless him and grant
him peace, took my hand and then said, "Mu'adh!' 'At your service!' I said.
He said, 'I love you.' I replied, 'And, by Allah, I love you.' He asked,
'Shall I teach you some words to say at the end of your prayer?' 'Yes,'
I replied. He said, 'Say:
"O Allah, help me to remember You and thank You
and help me to the best manner of worshipping You."'"
