عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ الْيَمِينُ الْكَاذِبَةُ مُنْفِقَةٌ لِلسِّلْعَةِ مُمْحِقَةٌ لِلْكَسْبِ وَفِي لَفْظٍ لِلْبَرَكَةِ
Narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: A false oath may sell the goods, but it erases the blessing of the earnings.
