- Question: What is the difference between taking out shaatnez from the collar of a four cornered garment after one has already tied tzitzis on it and removing an oath from the garment you swore you wouldn’t wear after you put tzitzis on it, according to the Pri Megadim?
Background:
A. The Pri Megadim (Mishbetzos Zahav 18:1) says that if one first put on tzitzis onto the garment and then removed the shaatnez one has to restring the tzitzis because the Torah says that one has to put on tzitzis on a garment ready to be worn, not make it obligated in tzitzis once the strings are already on, therefore if it has shaatnez on it, it is not wearable yet.
B. The Imray Binah mentions the case of a garment that one has sworn not to wear and then gets his oath annulled after putting on tzitzis. Why wouldn’t that be an issue of making it wearable after tzitzis is tied on it just like the shaatnez case?
Answer: The garment with shaatnez is forbidden to everyone so it is totally unwearable until fixed but the garment he swore not to wear is only forbidden to the one who made the oath but is permited to anyone else so it is considered ready to have tzitzis put on even before the owner is able to wear it. You can also say that even if it was forbidden by an oath to the entire world it is different because it was a side issue which did not make it wearable but shaatnez is a fundamental issue in the garment itself so you must first take care of the issue then tie on the tzitzis.
