[Machine] There was a man from the Ansar who was constantly deceived in his business transactions. There was filthiness in his speech, so he complained to the Messenger of Allah ﷺ about the oppression he faced. The Messenger of Allah ﷺ said to him, "If you make a transaction, say 'no deception.' " Ibn Umar said, "By Allah, it is as if I can still hear him saying it with his tongue."  

كَانَ رَجُلٌ مِنَ الْأَنْصَارِ لَا يَزَالُ يُغْبَنُفِي الْبُيُوعِ وَكَانَتْ فِي لِسَانِهِ لُوثَةٌ فَشَكَا إِلَى رَسُولِ اللهِ ﷺ مَا يَلْقَى مِنَ الْغَبْنِ فَقَالَ لَهُ رَسُولُ اللهِ ﷺ إِذَا أَنْتَ بَايَعْتَ فَقُلْ لَا خِلَابَةَ قَالَ يَقُولُ ابْنُ عُمَرَ فَوَاللهِ لَكَأَنِّي أَسْمَعُهُ يُبَايِعُ وَيَقُولُ لَا خِلَابَةَ يُلَجْلِجُ بِلِسَانِهِ
