A Practical Illustration of the Quality of Al-Amaanah (Returning the Trust) From Abdullah Ibn Al-Mubaarak

Al-Hasan bin Arafah said: Ibn al-Mubarak said to me, "I borrowed a pen in the land of Shaam and then went to return it. However, when I approached Marw (after leaving Shaam), I noticed it was still with me [he must have forgotten]. So I returned to Shaam until I returned it to its owner." Al-Siyar of al-Dhahabi (8/395).
