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."  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ الْحَلِفُ مُنَفِّقَةٌ لِلسِّلْعَةِ مُمْحِقَةٌ لِلْبَرَكَةِ  

Swearing produces a ready sale for a commodity, but blots out the blessing.  

أَنَّسَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ الْحَلِفُ مَنْفَقَةٌ لِلسِّلْعَةِ مَمْحَقَةٌ لِلرِّبْحِ  

"Taking oaths may help you to make a sale but it takes (blessing) away from the earnings "(Sahih )  

عَنِ النَّبِيِّ ﷺ قَالَ الْحَلِفُ مَنْفَقَةٌ لِلسِّلْعَةِ مَمْحَقَةٌ لِلْكَسْبِ  

[Machine] The Messenger of Allah ﷺ said: "The false oath is detrimental to the merchandise and destructive to earnings." And Ibn Ja'far said: "It brings blessings."  

قَالَ رَسُولُ اللهِ ﷺ الْيَمِينُ الْكَاذِبَةُ مَنْفَقَةٌ لِلسِّلْعَةِ مَمْحَقَةٌ لِلْكَسْبِ وَقَالَ ابْنُ جَعْفَرٍ للْبَرَكَة  

"Taking oaths may help you to make a sale but it takes (blessing) away from the earnings "(Sahih ) (Using translation from Nasāʾī 4461)   

النَّبِيَّ ﷺ الْيَمِينُ الْكَاذِبَةُ مَنْفَقَةٌ لِلسِّلْعَةِ مَمْحَقَةٌ لِلْكَسْبِ  

"Taking oaths may help you to make a sale but it takes (blessing) away from the earnings "(Sahih ) (Using translation from Nasāʾī 4461)  

عَنِ النَّبِيِّ ﷺ قَالَ «الْحَلِفُ مَنْفَقَةٌ لِلسِّلْعَةِ مَمْحَقَةٌ لِلْكَسْبِ»  

"Taking oaths may help you to make a sale but it takes (blessing) away from the earnings "(Sahih ) (Using translation from Nasāʾī 4461)   

النَّبِيَّ ﷺ الْيَمِينُ الْكَاذِبَةُ مَنْفَقَةٌ لِلسِّلْعَةِ مَمْحَقَةٌ لِلْكَسْبِ  

"إِن الإيمَانَ مَنْفَقَةٌ لِلسلعَة، مَمْحَقة للمالِ".  

"اليَمِينُ الكَاذبَةُ مَنْفَقَةٌ للسِّلعَةِ مَمْحَقَةٌ للكَسْبِ".  

"اليَمينُ الكَاذِبَةُ مَنْفَقَةٌ للسِّلعِةِ مَمْحَقَةٌ للبَرَكَةِ".
