The story of the people of Najran (Christians)
Sahih Bukhari
حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، قَالَ سَمِعْتُ أَبَا إِسْحَاقَ، عَنْ صِلَةَ بْنِ زُفَرَ، عَنْ حُذَيْفَةَ ـ رضى الله عنه ـ قَالَ جَاءَ أَهْلُ نَجْرَانَ إِلَى النَّبِيِّ صلى الله عليه وسلم فَقَالُوا ابْعَثْ لَنَا رَجُلاً أَمِينًا. فَقَالَ " لأَبْعَثَنَّ إِلَيْكُمْ رَجُلاً أَمِينًا حَقَّ أَمِينٍ ". فَاسْتَشْرَفَ لَهُ النَّاسُ، فَبَعَثَ أَبَا عُبَيْدَةَ بْنَ الْجَرَّاحِ.
Narrated Hudhaifa: The people of Najran came to the Prophet (ﷺ) and said, "Send an honest man to us." The Prophet (ﷺ) said, "I will send to you an honest man who is really trustworthy." Everyone of the (Muslim) people hoped to be that one. The Prophet (ﷺ) then sent Abu Ubaida bin Al-Jarrah.
