Narrator:Abu Hurayrah
وَعَنْ أَبِي هُرَيْرَةَ قَالَ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: «الْحلف منفقعة للسلعة ممحقة للبركة»
Abu Huraira said he heard God's Messenger say, “Swearing produces a ready sale for a commodity, but blots out the blessing.” (Bukhari and Muslim.)
