Questions: One of our teachers encourages us to write B”H on the top of our work, while another teacher told us that we should avoid doing so. Which is right?
Answer: The
Gemara (Rosh Hashana 18b) relates that the Yevanim decreed that
the Jewish people must not mention Hashem’s Name. The Chashmonaim ruled
that every letter they wrote should contain Hashem’s Name. Nonetheless, the
sages revoked this rule, fearing that these letters would end up being
discarded. Thus, the Rema (YD 276:13) writes that one must be careful not to
write sheimos in letters.
R’ Ovadia
Yosef (Yechave Daas 3:78) quotes the Chida who writes that one may write
abbreviations even if they refer to Hashem. While the Rogatchover Gaon (Tzafnas
Paneach 196) disagrees, R’ Ovadia writes that writing ב"ה
on the top of letters is an ancient minhag and is permissible.
However, R’
Moshe Feinstein (Igros Moshe YD 2:138) writes that while he is not
concerned about the letters being destroyed, it is not necessarily appropriate
to write ב"ה on a secular letter.
R’ Moshe Sternbuch (Teshuvos Vehanahagos 1:640) adds that the Vilna Gaon did
not write this on his letters. Nonetheless, they write that those that do want
to write something, should rather write בס"ד,
standing for bisyata dishmaya, with help from heaven (see
Aruch Hashulchan YD 276:28).
In conclusion, there are different practices regarding writing B”H on the top of a paper. Many Chassidim are particular to do so, some choose to write BS”D instead while others avoid writing anything.
