(7) باب حُكْمِ بَيْعِ الْمُصَرَّاةِ
Abu Huraira (Allah be pleased with him) reported Allah's Messenger (ﷺ) as saying:
He who buys a goat with its udder tied up has the option to retain the goat if he so desires or return it within three days, and in case he returns it he should do so along with a sa' of dates.
