مَن باعَ وَ اشْتَرى فلْيَجْتَنِبْ خَمسَ خِصالٍ، وَ إلّا فلا يَبيعَنَّ وَ لا يَشْتَرِيَنَّ: الرِّبا، وَ الحَلْفَ، وَ كِتْمانَ العَيبِ، وَ الحمدَ إذا باعَ، وَ الذَّمَّ إذا اشْتَرى.
The Prophet Muhammad (S):
Whoever sells or buys must avoid five habits, or he should not sell or buy at all: usury, [false] oaths, hiding the defects [of merchandise], praising what he sells, and showing disapproval for what he intends to buy.
