[Machine] That the boy swore to him, "Indeed, I have sold him," and he has a hidden illness that only he knows. So Abdullah refused to swear to him, and the slave returned. Abdullah bin Umar then sold him for one thousand and five hundred dirhams. Malik said that the agreed-upon matter among us is that whoever sells a slave, a child, or an animal with a declaration of innocence, then he is declared innocent of all defects, except if he knew of a defect and concealed it. If he knew of a defect and concealed it, his declaration of innocence is of no benefit to him, and what he sold is returned to him. We have also narrated from Ash-Shafi'i that he said regarding a man who sells a slave or any animal with a declaration of innocence from defects, "What we rely upon, and Allah knows best, is the verdict of Uthman ibn Affan, that he is innocent of every defect that he did not know, and he is not declared innocent of a defect that he knew, and the seller did not describe him."
