"I came to the Prophet and said to him: 'I pledge to you to hear and obey in what I like and what I dislike.' The Prophet said: 'Can you do that, O Jarir,' or, 'Are you able for that?' He said: Say: As much as I can.' So he accepted my pledge (for that), and that I be sincere toward every Muslim." (Using translation from Nasāʾī 4174)  

جَرِيرٌ أَتَيْتُ رَسُولَ اللهِ ﷺ فَقُلْتُ لَهُ أُبَايِعُكَ عَلَى السَّمْعِ وَالطَّاعَةِ فِيمَا أَحْبَبْتُ وَفِيمَا كَرِهْتُ قَالَ النَّبِيُّ ﷺ أَوَ تَسْتَطِيعُ ذَلِكَ يَا جَرِيرُ أَوَ تُطِيقُ ذَلِكَ؟ قَالَ قُلْ مَا اسْتَطَعْتُ فَبَايَعَنِي وَالنُّصْحِ لِكُلِّ مُسْلِمٍ
