I heard Messenger of Allah ﷺ say: Swearing produces a ready sale for a commodity but blots out the blessing. The narrator Ibn al-Sarh said: "for earning". He also narrated this tradition from Sa'id b. al-Musayyab on the authority of Abu Hurairah from the Prophet ﷺ.  

أبو داود:٣٣٣٥حَدَّثَنَا أَحْمَدُ بْنُ عَمْرِو بْنِ السَّرْحِ حَدَّثَنَا ابْنُ وَهْبٍ ح وَحَدَّثَنَا أَحْمَدُ بْنُ صَالِحٍ حَدَّثَنَا عَنْبَسَةُ عَنْ يُونُسَ عَنِ ابْنِ شِهَابٍ قَالَ قَالَ ابْنُ الْمُسَيَّبِ إِنَّ أَبَا هُرَيْرَةَ قَالَ

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ الْحَلِفُ مَنْفَقَةٌ لِلسِّلْعَةِ مَمْحَقَةٌ لِلْبَرَكَةِ قَالَ ابْنُ السَّرْحِ لِلْكَسْبِ وَقَالَ عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ عَنْ أَبِي هُرَيْرَةَ عَنِ النَّبِيِّ ﷺ

I heard Messenger of Allah ﷺ saying, "The swearing (by the seller) may persuade the buyer to purchase the goods but that will be deprived of Allah's blessing."  

البخاري:٢٠٨٧حَدَّثَنَا يَحْيَى بْنُ بُكَيْرٍ حَدَّثَنَا اللَّيْثُ عَنْ يُونُسَ عَنِ ابْنِ شِهَابٍ قَالَ ابْنُ الْمُسَيَّبِ إِنَّ أَبَا هُرَيْرَةَ ؓ قَالَ

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ الْحَلِفُ مُنَفِّقَةٌ لِلسِّلْعَةِ مُمْحِقَةٌ لِلْبَرَكَةِ
