"The Messenger of Allah ﷺ took my hand and said: 'I love you, O Mu'adh!' I said: 'And I love you, O Messenger of Allah ﷺ.' Then the Messenger of Allah ﷺ said: 'Never forget to say in every prayer: Rabbi a'inni 'ala dhikrika wa shukrika wa husni 'ibadatik (My Lord, help me to remember You, give thanks to You and worship You well.)"
أَخَذَ بِيَدِي رَسُولُ اللَّهِ ﷺ فَقَالَ: «إِنِّي لأُحِبُّكَ يَا مُعَاذُ۔» فَقُلْتُ: وَأَنَا أُحِبُّكَ يَا رَسُولَ اللَّهِ۔ فَقَالَ رَسُولُ اللَّهِ ﷺ: «فَلاَ تَدَعْ أَنْ تَقُولَ فِي كُلِّ صَلاَةٍ (رَبِّ أَعِنِّي عَلَى ذِكْرِكَ وَشُكْرِكَ وَحُسْنِ عِبَادَتِكَ۔)»
