وَعَن قيس بن أبي غَرزَة
قَالَ: كُنَّا نُسَمَّى فِي عَهْدِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ السَّمَاسِرَةَ فَمَرَّ بِنَا رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَسَمَّانَا بِاسْمٍ هُوَ أَحْسَنُ مِنْهُ فَقَالَ: «يَا مَعْشَرَ التُّجَّارِ إِنَّ الْبَيْعَ يَحْضُرُهُ اللَّغْوُ وَالْحَلِفُ فَشُوبُوهُ بِالصَّدَقَةِ»
In the time of God’s Messenger we used to be called brokers, but God’s Messenger came upon us one day and called us by a better name than that, saying, “Company of merchants, unprofitable speech and swearing have a place in business dealing, so mix it with sadaqa. Abu Dawud, Tirmidhi, Nasai and.”
