ذِكْرُ الزَّجْرِ عَنْ أَنْ يُنْفِقَ الْمَرْءُ سِلْعَتَهُ بِالْحَلِفِ الْكَاذِبَةِ
"Taking oaths may help you to make a sale but it takes (blessing) away from the earnings "(Sahih ) (Using translation from Nasāʾī 4461)
سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ «الْيَمِينُ الْكَاذِبَةُ مَنْفَقَةٌ لِلسِّلْعَةِ مَمْحَقَةٌ لِلْكَسْبِ»
