Uqba b. 'Amir al-Juhani reported:
وَحَدَّثَنَاهُ أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ ، حَدَّثَنَا زَيْدُ بْنُ الْحُبَابِ ، حَدَّثَنَا مُعَاوِيَةُ بْنُ صَالِحٍ ، عَنْ رَبِيعَةَ بْنِ يَزِيدَ ، عَنْ أَبِي إِدْرِيسَ الْخَوْلاَنِيِّ ، وَأَبِي، عُثْمَانَ عَنْ جُبَيْرِ بْنِ نُفَيْرِ بْنِ مَالِكٍ الْحَضْرَمِيِّ ، عَنْ عُقْبَةَ بْنِ عَامِرٍ الْجُهَنِيِّ ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم . قَالَ فَذَكَرَ مِثْلَهُ غَيْرَ أَنَّهُ قَالَ " مَنْ تَوَضَّأَ فَقَالَ أَشْهَدُ أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ وَحْدَهُ لاَ شَرِيكَ لَهُ وَأَشْهَدُ أَنَّ مُحَمَّدًا عَبْدُهُ وَرَسُولُهُ " .
Verily the Messenger of Allah (ﷺ) said and then narrated (the hadith) like one (mentioned above) except (this) that he said: He who performed ablution and said: I testify that there is no god but Allah, the One, there is no associate with Him and I testify that Muhammad is His servant and His Messenger.
