[Machine] He heard Ibn Umar say that a man mentioned to the Messenger of Allah ﷺ that he was being deceived in his trade transactions, so the Messenger of Allah ﷺ said to him, "If you have entered into a transaction, then say 'no deception.’"
أَنَّهُ سَمِعَ ابْنَ عُمَرَ يَقُولُ ذَكَرَ رَجُلٌ لِرَسُولِ اللهِ ﷺ أَنَّهُ يُخْدَعُ فِي الْبُيُوعِ فَقَالَ لَهُ رَسُولُ اللهِ ﷺ مَنْ بَايَعْتَ فَقُلْ لَا خِلَابَةَ
Yahya related to me from Malik from Abdullah ibn Dinar from Abdullah ibn Umar that a man mentioned to the Messenger of Allah ﷺ that he was always being cheated in business transactions. The Messenger of Allah ﷺ said, "When you enter a transaction, say, 'No trickery.' So whenever that man entered a transaction, he would say, 'No trickery.' "
أَنَّ رَجُلاً ذَكَرَ لِرَسُولِ اللَّهِ ﷺ أَنَّهُ يُخْدَعُ فِي الْبُيُوعِ فَقَالَ رَسُولُ اللَّهِ ﷺ إِذَا بَايَعْتَ فَقُلْ لاَ خِلاَبَةَ قَالَ فَكَانَ الرَّجُلُ إِذَا بَايَعَ يَقُولُ لاَ خِلاَبَةَ
