It was narrated that Nafey said: I used to send trade goods to Sham and Egypt, then I prepared to send tra?e goods to 'Iraq. I went to 'Aishah, the Mother of the Believers, and said to her. "0 Mother of the Believers! I used to send trade goods to Sham and I am preparing to send trade goods to 'Iraq." She said. "Do not do that. What is wrong with the way you have been doing it? I heard the Messenger of Allah P.B.U.H say. 'If Allah causes provision to come to one of you through a certain means, he should not leave it unless it changes or deteriorates." (Da'if)
