Nafi' says that I used to trade in Shaam or Egypt. Once, I prepared to go to Iraq, but before departing, I presented myself before Umm al-Mu'mineen, Hazrat Aisha (may Allah be pleased with her), and said to her, "O Umm al-Mu'mineen! I have prepared to go to Iraq." She said, "Why are you leaving your place of trade?" I heard the Prophet (peace and blessings be upon him) say: "When the sustenance of any one of you is attached to something, he should not leave it unless there is a change in it or it becomes corrupted." However, I still went to Iraq. Upon my return, I again presented myself before Umm al-Mu'mineen and said, "O Umm al-Mu'mineen! By Allah, I could not even recover my original capital." She said, "I had already narrated this hadith to you."
