Sahih Muslim 56
Sahih Muslim · Book 1: The Book of Faith · Clarifying that the religion is sincerity
It is narrated on the authority of Jarir that he observed:
حَدَّثَنَا سُرَيْجُ بْنُ يُونُسَ ، وَيَعْقُوبُ الدَّوْرَقِيُّ ، قَالاَ حَدَّثَنَا هُشَيْمٌ ، عَنْ سَيَّارٍ ، عَنِ الشَّعْبِيِّ ، عَنْ جَرِيرٍ ، قَالَ بَايَعْتُ النَّبِيَّ صلى الله عليه وسلم عَلَى السَّمْعِ وَالطَّاعَةِ فَلَقَّنَنِي " فِيمَا اسْتَطَعْتَ " . وَالنُّصْحِ لِكُلِّ مُسْلِمٍ . قَالَ يَعْقُوبُ فِي رِوَايَتِهِ قَالَ حَدَّثَنَا سَيَّارٌ .
I owed allegiance to the Messenger of Allah (may peace and blessings be upon him) on hearing ( is commands) and obeying (them) and the Prophet) instructed me (to act) as lay in my power, and sincerity and goodwill for every Muslim.
