حَدَّثَنَا عَبْدُ اللَّهِ حَدَّثَنِي أَبِي ثَنَا الْمُقْرِيءُ حَدَّثَنَا حَيْوَةُ قَالَ: سَمِعْتُ عُقْبَةَ بْنَ مُسْلِمٍ التُّجِيبِيَّ يَقُولُ حَدَّثَنِي أَبُو عَبْدِ الرَّحْمَنِ الْحُبُلِيُّ عَنِ الصُّنَابِحِيِّ عَنْ مُعَاذِ بْنِ جَبَلٍ رَضِيَ اللَّهُ عَنْهُ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ أَخَذَ بِيَدِهِ يَوْمًا ثُمَّ قَالَ: ((يَا مُعَاذُ! إِنِّي لَأُحِبُّكَ)) فَقَالَ لَهُ مُعَاذٌ: بِأَبِي أَنْتَ وَأُمِّي يَا رَسُولَ اللَّهِ! وَأَنَا أُحِبُّكَ، قَالَ: ((أُوْصِيكَ يَا مُعَاذُ! لَا تَدَعَنَّ فِي دُبُرِ كُلِّ صَلَاةٍ (وَفِي رِوَايَةٍ فِي كُلِّ صَلَاةٍ) أَنْ تَقُولَ اللَّهُمَّ أَعِنِّي عَلَى ذِكْرِكَ وَشُكْرِكَ وَحُسْنِ عِبَادَتِكَ)) قَالَ: وَأَوْصَى بِذَلِكَ مُعَاذٌ الصُّنَابِحِيَّ أَبَا عَبْدِ الرَّحْمَنِ، وَأَوْصَى أَبُو عَبْدِ الرَّحْمَنِ عُقْبَةَ بْنَ مُسْلِمٍ
It is narrated from Sayyiduna Mu'adh bin Jabal (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) once took his hand and said: O Mu'adh! Indeed, I love you. Sayyiduna Mu'adh (may Allah be pleased with him) said to him: May my parents be sacrificed for you, O Messenger of Allah! I also love you. Then the Prophet (peace and blessings be upon him) said: O Mu'adh! I advise you that you must never leave reciting this supplication after every prayer: "Allahumma a'inni 'ala dhikrika wa shukrika wa husni 'ibadatika." (O Allah! Help me to remember You, to thank You, and to worship You in the best manner). Sayyiduna Mu'adh (may Allah be pleased with him) gave this same advice to Abu Abdur Rahman Sanabihi, and he gave it to Uqbah bin Muslim.
