عَنْ أَبِي سَعِيدٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «التَّاجِرُ الصَّدُوقُ الْأَمِينُ معَ النبِّيِينَ والصِّدِّيقينَ والشهداءِ» . رَوَاهُ التِّرْمِذِيّ وَالدَّارَقُطْنِيّ. وَرَوَاهُ ابْنُ مَاجَهْ عَنِ ابْنِ عُمَرَ. وَقَالَ التِّرْمِذِيّ: هَذَا حَدِيث غَرِيب

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.
