حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ عُمَرَ بْنِ مَيْسَرَةَ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يَزِيدَ الْمُقْرِئُ، حَدَّثَنَا حَيْوَةُ بْنُ شُرَيْحٍ، قَالَ سَمِعْتُ عُقْبَةَ بْنَ مُسْلِمٍ، يَقُولُ حَدَّثَنِي أَبُو عَبْدِ الرَّحْمَنِ الْحُبُلِيُّ، عَنِ الصُّنَابِحِيِّ، عَنْ مُعَاذِ بْنِ جَبَلٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم أَخَذَ بِيَدِهِ وَقَالَ " يَا مُعَاذُ وَاللَّهِ إِنِّي لأُحِبُّكَ وَاللَّهِ إِنِّي لأُحِبُّكَ " . فَقَالَ " أُوصِيكَ يَا مُعَاذُ لاَ تَدَعَنَّ فِي دُبُرِ كُلِّ صَلاَةٍ تَقُولُ اللَّهُمَّ أَعِنِّي عَلَى ذِكْرِكَ وَشُكْرِكَ وَحُسْنِ عِبَادَتِكَ " . وَأَوْصَى بِذَلِكَ مُعَاذٌ الصُّنَابِحِيَّ وَأَوْصَى بِهِ الصُّنَابِحِيُّ أَبَا عَبْدِ الرَّحْمَنِ .
Mu'adh b. Jabal reported that the Messenger of Allah (ﷺ) caught his hand and said: By Allah, I love you, Mu'adh. I give some instruction to you. Never leave to recite this supplication after every (prescribed) prayer: "O Allah, help me in remembering You, in giving You thanks, and worshipping You well." Mu'adh willed this supplication to the narrator al-Sunabihi and al-Sunabihi to 'Abu Abd al-Rahman. [Sahih (Albani). Abu Dawud: 1522]
