حَدَّثَنِي يَحْيَى، عَنْ مَالِك، عَنْ
نَافِعٍ ، عَنْ
عَبْدِ اللَّهِ بْنِ عُمَرَ ، أَنّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ، قَالَ :
" الْمُتَبَايِعَانِ كُلُّ وَاحِدٍ مِنْهُمَا بِالْخِيَارِ عَلَى صَاحِبِهِ مَا لَمْ يَتَفَرَّقَا إِلَّا بَيْعَ الْخِيَارِ " .
It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "The seller and the buyer both have the option (to cancel the transaction) as long as they have not separated, except in the sale in which the option (of rescission) has been stipulated."
