"Allah will destroy Riba and will give increase for Sadaqat"
حَدَّثَنَا يَحْيَى بْنُ بُكَيْرٍ، حَدَّثَنَا اللَّيْثُ، عَنْ يُونُسَ، عَنِ ابْنِ شِهَابٍ، قَالَ ابْنُ الْمُسَيَّبِ إِنَّ أَبَا هُرَيْرَةَ ـ رضى الله عنه ـ قَالَ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ " الْحَلِفُ مُنَفِّقَةٌ لِلسِّلْعَةِ مُمْحِقَةٌ لِلْبَرَكَةِ ".
Narrated Abu Huraira: I heard Allah's Messenger (ﷺ) saying, "The swearing (by the seller) may persuade the buyer to purchase the goods but that will be deprived of Allah's blessing."
