A man came and said, "Messenger of Allah, fix the prices."He replied, "Rather, I will pray."Then another man came and said, "Messenger of Allah, fix the prices."He replied, "Rather, it is Allah who lowers and raises prices, and I truly hope to meet Allah while no one has a claim of injustice against me."
أن رجلا جاء، فقال: يا رسول الله سعر، فقال: بل أدعو. ثم جاءه رجل، فقال: يا رسول الله، سعر. فقال: بل الله يخفض ويرفع، وإني لأرجو أن ألقى الله وليس لأحد عندي مظلمة.
