In The Name of Allaah, The Most Merciful, The Bestower of Mercy.
Ali Bin Hafs Al-Bazzaar [rahimahullaah] said, ‘’Hafs Bin Abdir-Rahmaan [rahimahullaah] was a [business] partner of Abu Haneefah [rahimahullaah] and Abu Haneefah used to supply him with [merchandise]. Once he sent merchandise to Hafs and informed him that there was a defect in such and such thobe and that he should make it known before selling it. However, Hafs sold it and forgot to make that known and did not know who he sold it to. When Abu Haneefah knew about it, he gave charity equivalent to the price of all the merchandise.
