Hadith.4042 - It is narrated from Umar ibn Yazid, who said: I asked Abu Abdullah (as) about exchanging dirhams for dirhams, where one of them contains lead, but they are equal in weight.
Imam (as) said: "Repeat the question."
So I repeated it to him.
Then Imam (as) said: "Repeat it again."
I repeated it again, and Imam (as) said: "I see no harm in it."
