حَدَّثَنَا أَبُو نُعَيْمٍ حَدَّثَنَا سُفْيَانُ عَنْ عَبْدِ اللَّهِ بْنِ دِينَارٍ قَالَ سَمِعْتُ ابْنَ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا قَالَ قَالَ رَجُلٌ لِلنَّبِيِّ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ إِنِّي أُخْدَعُ فِي الْبُيُوعِ فَقَالَ إِذَا بَايَعْتَ فَقُلْ لَا خِلَابَةَ فَکَانَ الرَّجُلُ يَقُولُهُ
صحیح بخاری · Hadith 2407
Narrated Ibn `Umar: A man came to the Prophet and said, "I am often betrayed in bargaining." The Prophet advised him, "When you buy something, say (to the seller), 'No deception." The man used to say so afterwards.
