Hadisi 3853 — Sahih Muslim 21:52
حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، قَالَ قَرَأْتُ عَلَى مَالِكٍ عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " الْبَيِّعَانِ كُلُّ وَاحِدٍ مِنْهُمَا بِالْخِيَارِ عَلَى صَاحِبِهِ مَا لَمْ يَتَفَرَّقَا إِلاَّ بَيْعَ الْخِيَارِ " .
Ibn 'Umar (Allah be pleased with them) reported Allah's Messenger (ﷺ) as saying:Both parties in a business transaction have the right to annul it so long as they have not separated; except in transactions which have been made subject to the right of parties to annul them
Ibn 'Umar (Allah be pleased with thcm) reported Allah's Messenger (ﷺ) as saying:When two persons enter into a transaction, each of them has the right to annul it so long as they are not separated and are together (at the place of transaction) ; or if one gives the other the right (to annul the transaction) But if one gives the other the option, the transaction is made on this condition (i. e. one has the right to annul the transaction), it becomes binding. And if they are separated after they have made the bargain and none of them annulled it, even then the transaction is binding
Abdullah b. 'Umar (Allah be pleased with them) reported Allah's Messenger (ﷺ) as saying:When two persons enter into a transac. tion, each one of them has the right to annul it so long as they are not separated, or their transaction gives one another (as a condition) the right of annulling, and if their transaction, has the right of annulling it the transaction becomes binding. Ibn Abi Umar made this addition that whenever he (Ibn Umar) entered into a transaction with a person with the intention of not breaking it, he walked a while and then returned to him
Ibn Umar reported Allah's Messenger (ﷺ) as saying:There is no transaction between two persons entering a transaction until they separate, but only when there is an option to annul it
Hakim b. Hazim (Allah be pleased with him) reported Allah's Messenger (ﷺ) as saying:Both parties in a business transaction have the right to annul it so long as they have not separated; and if they speak the truth and make everything clear they will be blessed in their transaction; but if they tell a lie and conceal anything the blessing on their transaction will be blotted out
A hadith like this has been transmitted on the authority of Hakim b. Hizam (Imam Muslim) said:Hakim b. Hizam was born inside the Ka'ba and lived for one hundred and twenty years
Hadisi 3860 — Sahih Muslim 21:59
حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، وَيَحْيَى بْنُ أَيُّوبَ، وَقُتَيْبَةُ، وَابْنُ، حُجْرٍ قَالَ يَحْيَى بْنُ يَحْيَى أَخْبَرَنَا وَقَالَ الآخَرُونَ، حَدَّثَنَا إِسْمَاعِيلُ بْنُ جَعْفَرٍ، عَنْ عَبْدِ اللَّهِ بْنِ دِينَارٍ، أَنَّهُ سَمِعَ ابْنَ، عُمَرَ يَقُولُ ذَكَرَ رَجُلٌ لِرَسُولِ اللَّهِ صلى الله عليه وسلم أَنَّهُ يُخْدَعُ فِي الْبُيُوعِ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَنْ بَايَعْتَ فَقُلْ لاَ خِلاَبَةَ " . فَكَانَ إِذَا بَايَعَ يَقُولُ لاَ خِيَابَةَ.
Abdullah b. Dinar narrated that he heard Ibn 'Umar (Allah be pleased with them) saying:A man mentioned to the Messenger of Allah (ﷺ) that he was deceived in a business transaction, whereupon Allah's Messenger (ﷺ) said: When you enter into a transaction, say: There should be no attempt to deceive
