Hadith.3844 - It is narrated from Muhammad bin Qays who said: I said to Abu Abdillah (as), "A man gave another man one thousand dirhams in a partnership, and he unknowingly purchased his father with it." Imam (as) said: "He should be valued, and if his value exceeds by even one dirham, he shall be freed and shall work to repay the man's wealth."
