Arabic hadith text
أَخْبَرَنَا مُحَمَّدُ بْنُ عَلِيٍّ الْمَرْوَزِيُّ، قَالَ حَدَّثَنَا مُحْرِزُ بْنُ الْوَضَّاحِ، عَنْ إِسْمَاعِيلَ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " الْمُتَبَايِعَانِ بِالْخِيَارِ مَا لَمْ يَفْتَرِقَا إِلاَّ أَنْ يَكُونَ الْبَيْعُ كَانَ عَنْ خِيَارٍ فَإِنْ كَانَ الْبَيْعُ عَنْ خِيَارٍ فَقَدْ وَجَبَ الْبَيْعُ " .
Translation
Ibn Umar reported that the Messenger of Allah said: The two parties to a sale have the option as long as they have not separated, unless the sale was made subject to an option. If it was subject to an option and they choose to conclude it, then the sale is binding.
