حَدَّثَنَا أَبُو سَلَمَةَ أَخْبَرَنَا سُلَيْمَانُ بْنُ بِلَالٍ عَنْ عَبْدِ اللَّهِ بْنِ دِينَارٍ عَنِ ابْنِ عُمَرَ قَالَ ذُكِرَ لِلنَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ رَجُلٌ يُخْدَعُ فِي الْبَيْعِ فَقَالَ لَهُ مَنْ بَايَعْتَ فَقُلْ لَا خِلَابَةَ فَكَانَ يَقُولُ إِذَا بَايَعَ لَا خِلَابَةَ وَكَانَ فِي لِسَانِهِ رُتَّةٌ
مسند امام احمد بن حنبل · Hadith 5405
It was narrated that Ibn Umar said: Mention was made to the Prophet of a man who was often deceived in transactions and he (PBUH) said to him: "When you enter into a transaction, say: 'There should be no deceit." So he would say, when he entered into a transaction: There should be no deceit. And he had a speech impediment.
