“This is concerning my question before abu ‘Abd Allah (a.s.), about the case of a man who buys sacks made in Hirat, and in al-Quhiy. A man then buys from him ten cloths with the condition that he can choose every cloth, for a certain amount of profit, five or less or more. He (the Imam) said, ‘I do not like this sale. Consider if he cannot find in choosing anything other than five cloths and finds the rest the same.’ Imam’s son, ‘Isma’il said, ‘They have set a condition on him to take ten pieces’ and he repeated it several times. He (the Imam) said, ‘He has set up a condition to take the best. Consider if there is nothing more than five cloths and he finds the rest the same.’ He (the Imam) said, ‘I do not like this deal.’ He (the Imam) disliked it because of one party’s suffering loss.’”
