وعن أبي صفوان سويد بن قيس
رضي الله عنه قال: جلبت أنا ومخرمة العبدي بزًا من هجر، فجاءنا النبي صلى الله عليه وسلم فساومنا سراويل، وعندي وزان يزن بالأجر، فقال النبي صلى الله عليه وسلم للوزان «زن وأرجح»
Makhramah Al-Abdi and I procured some drapery from Hajar and brought them to Makkah. The Prophet (sallallahu alayhi wa sallam) came and bargained with us for some trousers and we sold them to him. We had a person who weighed the cloth in order to fix the price. The Prophet (sallallahu alayhi wa sallam) said to him, “Weigh and add a little to it.”.
