We were entrusted with the task of tending the camels. On my turn when I came back in the evening after grazing them in the pastures, I found Messenger of Allah ﷺ stand and address the people. I heard these words of his: If any Muslim performs ablution well, then stands and prays two rak'ahs setting about them with his heart as well as his face, Paradise would be guaranteed to him. I said: What a fine thing is this! And a narrator who was before me said: The first was better than even this. When I cast a glance, I saw that it was 'Umar who said: I see that you have just come and observed: If anyone amongst you performs the ablution, and then completes the ablution well and then says: I testify that there is no god but Allah and that Muhammad is the servant of Allah and His Messenger, the eight gates of Paradise would be opened for him and he may enter by whichever of them he wishes. (Using translation from Muslim 234a)   

كَانَتْ عَلَيْنَا رِعَايَةُ الْإِبِلِ فَحَانَتْ نَوْبَتِي فَرَوَّحْتُهَا بِعَشِيٍّ فَأَدْرَكْتُ رَسُولَ اللهِ ﷺ قَائِمًا يُحَدِّثُ النَّاسَ فَأَدْرَكْتُ مِنْ قَوْلِهِ مَا مِنْ مُسْلِمٍ يَتَوَضَّأُ فَيُحْسِنُ الْوُضُوءَ ثُمَّ يَقُومُ فَيُصَلِّي رَكْعَتَيْنِ فَيُقْبِلُ عَلَيْهِمَا بِقَلْبِهِ وَوَجْهِهِ إِلَّا وَجَبَ لَهُ الْجَنَّةُ قَالَ فَقُلْتُ مَا أَجْوَدَ هَذِهِ فَإِذَا قَائِلٌ بَيْنَ يَدِيَّ يَقُولُ الَّتِي قَبْلَهَا أَجْوَدُ فَنَظَرْتُ فَإِذَا عُمَرُ بْنُ الْخَطَّابِ ؓ قَالَ إِنِّي قَدْ رَأَيْتُكَ جِئْتَ آنِفًا قَالَ مَا مِنْكُمْ مِنْ أَحَدٍ يَتَوَضَّأُ ثُمَّ يَقُولُ أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللهُ وَأَشْهَدُ أَنْ مُحَمَّدًا عَبْدُهُ وَرَسُولُهُ إِلَّا فُتِحَتْ لَهُ أَبْوَابُ الْجَنَّةِ الثَّمَانِيَةَ يَدْخُلُ مِنْ أَيِّهَا شَاءَ لَفْظُ حَدِيثِ ابْنِ مَهْدِيٍّ  

[Machine] The Messenger of Allah ﷺ said, "Whoever performs ablution and perfects their wudu, then says, 'I bear witness that there is no deity worthy of worship except Allah, alone with no partner, and that Muhammad is His servant and Messenger,' the eight gates of Paradise will be opened for them, and they may enter through whichever gate they choose." Abu Abdullah informed us, Abu Bakr ibn Abdullah informed me, Hasan ibn Sufyan informed me, Abu Bakr ibn Abi Shaybah informed me, Zaid ibn Al-Hubab mentioned it with his chain of narration, and Abu Uthman mentioned it from Jubayr ibn Nufair ibn Malik Al-Hadrami from Uqbah ibn Amir.  

قَالَ رَسُولُ اللهِ ﷺ مَنْ تَوَضَّأَ فَأَحْسَنَ الْوُضُوءَ ثُمَّ قَالَ أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللهُ وَحْدَهُ لَا شَرِيكَ لَهُ وَأَنَّ مُحَمَّدًا عَبْدُهُ وَرَسُولُهُ فُتِحَتْ لَهُ ثَمَانِيَةُ أَبْوَابِ الْجَنَّةِ يَدْخُلُ مِنْ أَيِّهَا شَاءَ 370 وَأَخْبَرَنَا أَبُو عَبْدِ اللهِ أَخْبَرَنِي أَبُو بَكْرِ بْنُ عَبْدِ اللهِ أنا الْحَسَنُ بْنُ سُفْيَانَ أنا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ نا زَيْدُ بْنُ الْحُبَابِ فَذَكَرَهُ بِإِسْنَادِهِ وَقَالَ وَأَبُو عُثْمَانَ عَنْ جُبَيْرِ بْنِ نُفَيْرِ بْنِ مَالِكٍ الْحَضْرَمِيِّ عَنْ عُقْبَةَ بْنِ عَامِرٍ
