I used to send trade goods to Sham and Egypt, then I prepared to send trade goods to 'Iraq. I went to 'Aishah, the Mother of the Believers, and said to her: " O 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 ﷺ 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."
كُنْتُ أُجَهِّزُ إِلَى الشَّامِ وَإِلَى مِصْرَ فَجَهَّزْتُ إِلَى الْعِرَاقِ فَأَتَيْتُ عَائِشَةَ أُمَّ الْمُؤْمِنِينَ فَقُلْتُ لَهَا يَا أُمَّ الْمُؤْمِنِينَ كُنْتُ أُجَهِّزُ إِلَى الشَّامِ فَجَهَّزْتُ إِلَى الْعِرَاقِ فَقَالَتْ لاَ تَفْعَلْ مَالَكَ وَلِمَتْجَرِكَ فَإِنِّي سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ إِذَا سَبَّبَ اللَّهُ لأَحَدِكُمْ رِزْقًا مِنْ وَجْهٍ فَلاَ يَدَعْهُ حَتَّى يَتَغَيَّرَ لَهُ أَوْ يَتَنَكَّرَ لَهُ
