حَدَّثَنَا أَحْمَدُ بْنُ عَبْدِ الرَّحْمَنِ بْنِ وَهْبِ بْنِ مُسْلِمٍ حَدَّثَنَا عَمِّى عَبْدُ اللَّهِ بْنُ وَهْبٍ حَدَّثَنَا عَمْرُو بْنُ الْحَارِثِ حَدَّثَنِى بُكَيْرٌ عَنْ بُسْرِ بْنِ سَعِيدٍ عَنْ جُنَادَةَ بْنِ أَبِى أُمَيَّةَ قَالَ دَخَلْنَا عَلَى عُبَادَةَ بْنِ الصَّامِتِ وَهُوَ مَرِيضٌ فَقُلْنَا حَدِّثْنَا أَصْلَحَكَ اللَّهُ بِحَدِيثٍ يَنْفَعُ اللَّهُ بِهِ سَمِعْتَهُ مِنْ رَسُولِ اللَّهِ -صلى الله عليه وسلم-. فَقَالَ دَعَانَا رَسُولُ اللَّهِ -صلى الله عليه وسلم- فَبَايَعْنَاهُ فَكَانَ فِيمَا أَخَذَ عَلَيْنَا أَنْ بَايَعَنَا عَلَى السَّمْعِ وَالطَّاعَةِ فِى مَنْشَطِنَا وَمَكْرَهِنَا وَعُسْرِنَا وَيُسْرِنَا وَأَثَرَةٍ عَلَيْنَا وَأَنْ لاَ نُنَازِعَ الأَمْرَ أَهْلَهُ قَالَ « إِلاَّ أَنْ تَرَوْا كُفْرًا بَوَاحًا عِنْدَكُمْ مِنَ اللَّهِ فِيهِ بُرْهَانٌ ».

It was narrated that Junadah bin Abi Umayyah said: "We entered upon 'Ubadah bin As-Samit when he was sick. We said: 'Tell us, may Allah give you health, a Hadith by means of which Allah may benefit us, that you heard from the Messenger of Allah (s.a.w).' He said: 'The Messenger of Allah (s.a.w) called us, and we swore allegiance to him, and among the pledges that he took from us was that we would hear and obey, whether we liked it or not, at times of hardship and times of ease, even if the leaders acted in a selfish manner, and promising not to contest any position of authority, and he said: "Unless you see blatant Kufr (disbelief), for which you have proof from Allah."
