Mu'adh (bin Jabal) (May Allah be pleased with him) reported: Messenger of Allah (ﷺ) held my hand and said, "O Mu'adh, By Allah, I love you and advise you not to miss supplicating after every Salat (prayer) saying: 'Allahumma a'inni 'ala dhikrika wa shukrika, wa husni 'ibadatika,' (O Allah, help me remember You, expressing gratitude to You and worship You in the best manner)". [Hadith Sahih] . [Abu Dawud and An- Nasa'i] .
