عَنْ جَابِرٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: رَحِمَ اللَّهُ رَجُلًا سَمْحًا إِذَا بَاعَ وَإِذَا اشْتَرَى وَإِذَا اقْتَضَى رَوَاهُ البُخَارِيّ

Abu Qatada reported God’s Messenger as saying, “Avoid much swearing while transacting business, for it produces a ready sale then blots out the blessing.” Muslim transmitted it.
