Huzaifa bin Yaman reported,
Aqib and Sayyid came to the Prophet ﷺ and said, "Send with us your trustworthy one."He replied, "I will send with you a trustworthy man, truly trustworthy."The people craned their necks hoping to be chosen, and he sent Abu Ubayda bin Jarra.The narrator said, whenever Abu Ishaq related this hadith from Sila, he would say, "I heard it sixty years ago."This is a good and authentic hadith. It has also been narrated from Ibn Umar and Anas from the Prophet ﷺ that he said, "Every nation has a trustworthy one, and the trustworthy one of this nation is Abu Ubayda bin Jarra."
Tirmidhi 3757B
Sahihحدثنا محمود بن غيلان: حدثنا وكيع: حدثنا سفيان عن أبي إسحاق، عن صلة بن زفر،
عن حذيفة بن اليمان قال
جاء العاقب والسيد إلى النبي فقالا: ابعث معنا أمينك، قال: فإني سأبعث معكم أمينا حق أمين، فأشرف لها الناس فبعث أبا عبيدة قال: وكان أبو إسحاق إذا حدث بهذا الحديث عن صلة قال: سمعته منذ ستين سنة. هذا حديث حسن صحيح. وقد روي عن ابن عمر وأنس عن النبي ﷺ أنه قال: لكل أمة أمين وأمين هذه الأمة أبو عبيدة بن الجراح.
