Chapter 22: Swearing Oaths And Lying When One Does Not Believe In What He Is Swearing About - كتاب الأيمان والنذور
أَخْبَرَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ يَزِيدَ، عَنْ سُفْيَانَ، عَنْ عَبْدِ الْمَلِكِ، وَعَاصِمٍ، وَجَامِعٍ، عَنْ أَبِي وَائِلٍ، عَنْ قَيْسِ بْنِ أَبِي غَرَزَةَ، قَالَ كُنَّا نَبِيعُ بِالْبَقِيعِ فَأَتَانَا رَسُولُ اللَّهِ صلى الله عليه وسلم وَكُنَّا نُسَمَّى السَّمَاسِرَةَ فَقَالَ " يَا مَعْشَرَ التُّجَّارِ " . فَسَمَّانَا بِاسْمٍ هُوَ خَيْرٌ مِنِ اسْمِنَا ثُمَّ قَالَ " إِنَّ هَذَا الْبَيْعَ يَحْضُرُهُ الْحَلِفُ وَالْكَذِبُ فَشُوبُوهُ بِالصَّدَقَةِ " .
It was narrated that Qais bin Abi Gharazah said:
"We used to sell in Al-Baqi, and the Messenger of Allah came to us. We used to be called Samasir (brokers) but he said: 'O merchants!' And called us by a name that was better than our name. Then he said: 'This selling involves (false) oaths and lies, so mix some charity with it.'"
