باب حُكْمِ بَيْعِ الْمُصَرَّاةِ ‏‏
Sahih Muslim 1524 e

Ayyub narrated with the same chain of transmitters but with this change of words:

" He who buys a goat has the option...."
وَحَدَّثَنَاهُ ابْنُ أَبِي عُمَرَ، حَدَّثَنَا عَبْدُ الْوَهَّابِ، عَنْ أَيُّوبَ، بِهَذَا الإِسْنَادِ غَيْرَ أَنَّهُ قَالَ ‏ "‏ مَنِ اشْتَرَى مِنَ الْغَنَمِ فَهُوَ بِالْخِيَارِ ‏"‏ ‏.‏
