I asked Ibn Abbas about currency exchange, and he said, "Hand to hand?"I said, "Yes."He said, "Then there is no harm in it."So I informed Abu Saeed, saying, "I asked Ibn Abbas about currency exchange, and he said, 'Hand to hand?' I said, 'Yes.' He said, 'Then there is no harm in it.'"Abu Saeed replied, "Did he really say that? We will write to him so that he does not give you such a verdict. By Allah, one of the young servants of the Messenger of Allah ﷺ brought him some dates, and he found them unfamiliar. He said, 'These do not seem to be from the dates of our land.'The young man said, 'There was something wrong with the dates of our land this year, so I took these and gave some extra in exchange.'The Prophet ﷺ said, 'You have given more, you have committed usury. Do not go near this again. If you have any doubt about your dates, then sell them, and then buy the kind of dates you want.'"
سألت ابن عباس عن الصرف، فقال: أيدا بيد؟ قلت: نعم. قال: فلا بأس به فأخبرت أبا سعيد، فقلت: إني سألت ابن عباس عن الصرف، فقال: أيدا بيد؟ قلت: نعم. قال: فلا بأس به. قال: أوقال ذلك! إنا سنكتب إليه فلا يفتيكموه. قال: فوالله لقد جاء بعض فتيان رسول الله ﷺ بتمر، فأنكره، فقال: كأن هذا ليس من تمر أرضنا. قال: كان في تمر أرضنا- أو في تمرنا- العام بعض الشيء، فأخذت هذا، وزدت بعض الزيادة. فقال: أضعفت أربيت، لا تقربن هذا، إذا رابك من تمرك شيء فيعه، ثم اشتر الذي تريد من التمر.
