Ibn 'Umar said that if anyone buys a garment for ten dirhams among which is one unlawfully acquired, God most high will not accept prayer from him as long as he wears it. He then put a finger in each ear and said, “May they become deaf if the Prophet was not the one I heard say it!” Baihaqi transmitted it in Shu'ab al-iman , saying that its isnad is weak.
