One day our Prophet (blessings and peace be upon him) held Muaz b. Jabal’s hand and said:
“Muaz! As God is my witness, I truly love you!” Upon this, His Excellency Muaz told our Prophet:
“O Messenger of God! I truly love you, too.” Our Prophet continued: Muaz! I strongly recommend
for you to recite this supplication after each prayer.
اَللّٰهُمَّ أَعِنّ۪ي عَلٰى ذِكْرِكَ وَشُكْرِكَ وَحُسْنِ عِبَادَتِكَ
“O My Lord! Help me to remember You and recite Your Name in Your remembrance, to thank You for the bounties You provided, and to worship You in the way that befits You.”
(Abu Dawud, Witr 26)
