Arabic hadith text
حَدَّثَنَا أَحْمَدُ بْنُ سَعِيدٍ الْهَمْدَانِيُّ، حَدَّثَنَا ابْنُ وَهْبٍ، سَمِعْتُ مُعَاوِيَةَ، - يَعْنِي ابْنَ صَالِحٍ - يُحَدِّثُ عَنْ أَبِي عُثْمَانَ، عَنْ جُبَيْرِ بْنِ نُفَيْرٍ، عَنْ عُقْبَةَ بْنِ عَامِرٍ، قَالَ كُنَّا مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم خُدَّامَ أَنْفُسِنَا نَتَنَاوَبُ الرِّعَايَةَ رِعَايَةَ إِبِلِنَا فَكَانَتْ عَلَىَّ رِعَايَةُ الإِبِلِ فَرَوَّحْتُهَا بِالْعَشِيِّ فَأَدْرَكْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَخْطُبُ النَّاسَ فَسَمِعْتُهُ يَقُولُ ‏"‏مَا مِنْكُمْ مِنْ أَحَدٍ يَتَوَضَّأُ فَيُحْسِنُ الْوُضُوءَ ثُمَّ يَقُومُ فَيَرْكَعُ رَكْعَتَيْنِ يُقْبِلُ عَلَيْهِمَا بِقَلْبِهِ وَوَجْهِهِ إِلاَّ قَدْ أَوْجَبَ ‏"‏ ‏.‏ فَقُلْتُ بَخْ بَخْ مَا أَجْوَدَ هَذِهِ ‏.‏ فَقَالَ رَجُلٌ مِنْ بَيْنِ يَدَىَّ الَّتِي قَبْلَهَا يَا عُقْبَةُ أَجْوَدُ مِنْهَا ‏.‏ فَنَظَرْتُ فَإِذَا هُوَ عُمَرُ بْنُ الْخَطَّابِ فَقُلْتُ مَا هِيَ يَا أَبَا حَفْصٍ قَالَ إِنَّهُ قَالَ آنِفًا قَبْلَ أَنْ تَجِيءَ ‏"‏ مَا مِنْكُمْ مِنْ أَحَدٍ يَتَوَضَّأُ فَيُحْسِنُ الْوُضُوءَ ثُمَّ يَقُولُ حِينَ يَفْرُغُ مِنْ وُضُوئِهِ أَشْهَدُ أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ وَحْدَهُ لاَ شَرِيكَ لَهُ وَأَنَّ مُحَمَّدًا عَبْدُهُ وَرَسُولُهُ إِلاَّ فُتِحَتْ لَهُ أَبْوَابُ الْجَنَّةِ الثَّمَانِيَةُ يَدْخُلُ مِنْ أَيِّهَا شَاءَ ‏"‏ ‏.‏ قَالَ مُعَاوِيَةُ وَحَدَّثَنِي رَبِيعَةُ بْنُ يَزِيدَ عَنْ أَبِي إِدْرِيسَ عَنْ عُقْبَةَ بْنِ عَامِرٍ ‏.‏
Translation
‘Uqbah b. ‘Amir said

Ahmad ibn Sa'id al-Hamdani narrated to us, Ibn Wahb narrated to us, I heard Mu'awiyah - meaning Ibn Salih - narrating from Abu Uthman, from Jubayr ibn Nufayr, from 'Uqbah ibn 'Amir, who said: We were with the Messenger of Allah, peace and blessings be upon him, serving ourselves, taking turns in herding our camels. It was my turn to herd the camels, so I brought them back to rest in the evening, and I reached the Messenger of Allah, peace and blessings be upon him, while he was addressing the people, and I heard him saying: "There is no one among you who performs ablution, perfects his ablution, then stands and prays two rak'ahs, devoting his heart and face to them, except that he has made it obligatory." I said: "How excellent and wonderful is this!" Then a man in front of me who had come just before said: "What came before is even more wonderful, O 'Uqbah!" I looked, and behold, it was 'Umar ibn al-Khattab. I said: "What is it, O Abu Hafs?" He said: "He said just now before you came: "There is no one among you who performs ablution, perfects his ablution, and then says upon finishing his ablution: 'I bear witness that there is no god but Allah alone, with no partner, and that Muhammad is His servant and Messenger,' except that the eight gates of Paradise are opened for him, and he may enter through whichever of them he wishes." Mu'awiyah said: Rabi'ah ibn Yazid narrated to me from Abu Idris, from 'Uqbah ibn 'Amir.
