It was narrated from 'Ubadah bin Al-Walid bin 'Ubadah bin As-Samit, frim this father, that his grandfather said:"We pledged to the Messenger of Allah to hear and obey both in times of hardship and 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, and that we would speak the truth wherever we may be."
أَخْبَرَنَا مُحَمَّدُ بْنُ يَحْيَى بْنِ أَيُّوبَ، قَالَ حَدَّثَنَا عَبْدُ اللَّهِ بْنُ إِدْرِيسَ، عَنِ ابْنِ إِسْحَاقَ، وَيَحْيَى بْنِ سَعِيدٍ، عَنْ عُبَادَةَ بْنِ الْوَلِيدِ بْنِ عُبَادَةَ بْنِ الصَّامِتِ، عَنْ أَبِيهِ، عَنْ جَدِّهِ، قَالَ بَايَعْنَا رَسُولَ اللَّهِ صلى الله عليه وسلم عَلَى السَّمْعِ وَالطَّاعَةِ فِي الْعُسْرِ وَالْيُسْرِ وَالْمَنْشَطِ وَالْمَكْرَهِ وَأَنْ لاَ نُنَازِعَ الأَمْرَ أَهْلَهُ وَعَلَى أَنْ نَقُولَ بِالْحَقِّ حَيْثُ كُنَّا .
