Fine Qualities
Hudhaifa told that the people of Najran came to God's messenger and said, "Messenger of God, send us a trustworthy man." When he replied, "I shall certainly send you a trustworthy man who is genuinely trustworthy," the people[*] were looking to see if they would be appointed. He then sent Abu `Ubaida b. al-Jarrah. *i.e., the Prophet's companions. (Bukhari and Muslim.)
وَعَن حُذَيْفَة قَالَ: جَاءَ أَهْلُ نَجْرَانَ إِلَى رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالُوا: يَا رَسُولَ اللَّهِ ابْعَثْ إِلَيْنَا رَجُلًا أَمِينًا. فَقَالَ: «لَأَبْعَثَنَّ إِلَيْكُمْ رَجُلًا أَمِينًا حَقَّ أَمِينٍ» فَاسْتَشْرَفَ لَهَا الناسُ قَالَ: فَبعث أَبَا عبيدةَ بن الْجراح. مُتَّفق عَلَيْهِ
