Narrator:Qays ibn Abu Gharaza
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» . رَوَاهُ أَبُو دَاوُدَ وَالتِّرْمِذِيُّ وَالنَّسَائِيُّ وَابْنُ مَاجَهْ
Qais b. Abu Gharaza said :
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, Nasa’i and Ibn Majah transmitted it.
