Take the 2-minute tour ×  Say someone purchased clothing on
shabbat--knowing that it was a violation--can that clothing be
worn?  share|improve this question  1 Answer 1  Since you say
the purchaser knows his act was "a violation", I'll assume he's
Jewish. For the same reason, I won't discuss here a case in
which someone did a prohibited act without knowing that what he
was doing was wrong. (The rules are somewhat different in such a
case.) Thus, caveat lector: the below is about cases in which
the Shabas-violator knew he was violating Shabas.  If something
is cooked by a Jew on Shabas the cooked food cannot be eaten on
that Shabas, and is forbidden to him forever. (Shulchan Aruch
318:1.) The commentators note that the same is true for other
prohibitions, not just cooking.  But Beur Halacha ("אחת משאר
מלאכות", quoting Chaye Adam) says that if a forbidden act done
on an object did not physically change the object in any way
(e.g. something was carried), then it's prohibited only until
the close of Shabas, even
