Q. As a Chaplain I visit and tend to the needs incarcerated individuals. I brought a taalis to a Jewish inmate, and then his Gentile roommate also wanted one. As this may be an issue of chilul Hashem, and creating enmity, can I also provide one for him, since he is willing to pay for it?
A. Poskim permit in cases of need to sell a mezuza to a Gentile, when there is an understanding that he will keep it with proper decorum.
In this particular case, Horav Shlomo Miller’s Shlit’a opinion is that he may purchase a modern taalis shawl worn around the neck and usually made of synthetic materials, (often used by non- religious individuals or children). These prayer shawls, although they may look comely are likely not kosher and may not constitute a chefetz shel (object of) mitzva, that has to be kept with proper care. One should also be careful that the shawl does not display blessings or pesukim printed on it.
