Sunan an-Nasa'i 4154
It was narrated from Shu'bah, from Sayyar and Yahya bin Sa'eed that they heard 'Ubadah bin Al-Walid narrating from his father. Sayyar said:
"From his father," and Yahya said: "From his father," from his grandfather, whom said: 'We pledged to the Messenger of Allah to hear and obey during our hardship and our ease, when we felt energetic and when we felt tired, and when others are preferred over us, that we would not contend with the orders of whomever was entrusted with it, that we would stand firm for the truth wherever it may be, and that we would not fear the blame of any blamer for the sake of Allah." (Sahih)
Shu'bah said: "Sayyar did not mention this statement: 'Wherever it may be' while Yahya mentioned it." Shu'bah said: "If I have added anything to it, then it is from Sayyar or from Yahya."
أَخْبَرَنَا مُحَمَّدُ بْنُ الْوَلِيدِ، قَالَ حَدَّثَنَا مُحَمَّدٌ، قَالَ حَدَّثَنَا شُعْبَةُ، عَنْ سَيَّارٍ، وَيَحْيَى بْنِ سَعِيدٍ، أَنَّهُمَا سَمِعَا عُبَادَةَ بْنَ الْوَلِيدِ، يُحَدِّثُ عَنْ أَبِيهِ، - أَمَّا سَيَّارٌ فَقَالَ عَنْ أَبِيهِ، وَأَمَّا، يَحْيَى فَقَالَ عَنْ أَبِيهِ، عَنْ جَدِّهِ، - قَالَ بَايَعْنَا رَسُولَ اللَّهِ صلى الله عليه وسلم عَلَى السَّمْعِ وَالطَّاعَةِ فِي عُسْرِنَا وَيُسْرِنَا وَمَنْشَطِنَا وَمَكْرَهِنَا وَأَثَرَةٍ عَلَيْنَا وَأَنْ لاَ نُنَازِعَ الأَمْرَ أَهْلَهُ وَأَنْ نَقُومَ بِالْحَقِّ حَيْثُمَا كَانَ لاَ نَخَافُ فِي اللَّهِ لَوْمَةَ لاَئِمٍ ‏.‏ قَالَ شُعْبَةُ سَيَّارٌ لَمْ يَذْكُرْ هَذَا الْحَرْفَ حَيْثُمَا كَانَ وَذَكَرَهُ يَحْيَى ‏.‏ قَالَ شُعْبَةُ إِنْ كُنْتُ زِدْتُ فِيهِ شَيْئًا فَهُوَ عَنْ سَيَّارٍ أَوْ عَنْ يَحْيَى ‏.‏
