Arabic hadith text
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، أَخْبَرَنَا مَالِكٌ، عَنْ عَبْدِ اللَّهِ بْنِ دِينَارٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ ـ رضى الله عنهما ـ أَنَّ رَجُلاً، ذَكَرَ لِلنَّبِيِّ صلى الله عليه وسلم أَنَّهُ يُخْدَعُ فِي الْبُيُوعِ، فَقَالَ " إِذَا بَايَعْتَ فَقُلْ لاَ خِلاَبَةَ ".
Translation
Abdullah ibn Yusuf informed us: Malik informed us, from Abdullah ibn Dinar, from Abdullah ibn Umar, may Allah be pleased with them both: A man told the Prophet, peace and blessings be upon him, that he was being deceived in sales. He said, “When you make a sale, say: No deception.”
Translation notes
The brief formula لا خِلابة is rendered directly as No deception.
