(9) باب ذِكْرِ الاِخْتِلاَفِ عَلَى نَافِعٍ فِي لَفْظِ حَدِيثِهِ
It was narrated from Yahya bin Sa 'eed who said:
"I heard Nafi narrating from Ibn 'Umar, form the Messenger of Allah 'the two parties to a transaction both have the choice so long as they have not separated unless they have chosen to conclude the transaction. " Nafi said: ''When 'Abdullah bought something he like, he would leave straightaway."
