It was narrated that Mu'adhbin Jabal said: "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.)"

أَخْبَرَنَا يُونُسُ بْنُ عَبْدِ الأَعْلَى، قَالَ حَدَّثَنَا ابْنُ وَهْبٍ، قَالَ سَمِعْتُ حَيْوَةَ، يُحَدِّثُ عَنْ عُقْبَةَ بْنِ مُسْلِمٍ، عَنْ أَبِي عَبْدِ الرَّحْمَنِ الْحُبُلِيِّ، عَنِ الصُّنَابِحِيِّ، عَنْ مُعَاذِ بْنِ جَبَلٍ، قَالَ أَخَذَ بِيَدِي رَسُولُ اللَّهِ صلى الله عليه وسلم فَقَالَ ‏"‏ إِنِّي لأُحِبُّكَ يَا مُعَاذُ ‏"‏ ‏.‏ فَقُلْتُ وَأَنَا أُحِبُّكَ يَا رَسُولَ اللَّهِ ‏.‏ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ فَلاَ تَدَعْ أَنْ تَقُولَ فِي كُلِّ صَلاَةٍ رَبِّ أَعِنِّي عَلَى ذِكْرِكَ وَشُكْرِكَ وَحُسْنِ عِبَادَتِكَ ‏"‏ ‏.‏
