Questions: One of our teachers encourages us to write ב"ה at the top of our work, while another has advised against it. Which approach is correct?
Answer: The Gemara (Rosh Hashana 18b) relates that the Yevanim decreed that the Jewish
people must not mention Hashem’s Name. In response, the Chashmonaim
instituted that every letter should include Hashem’s Name. However, Chazal
later annulled this practice, fearing that such letters might ultimately be
discarded. As a result, the Rema (YD 276:13) rules that
one must take care not to write sheimos in letters.
R’ Ovadia Yosef (Yechave Daas 3:78) quotes the Chida, who permits writing abbreviations even if
they allude to Hashem’s Name. Although the Rogatchover Gaon (Tzafnas Paneach 196) disagrees, R’ Ovadia maintains that
writing ב"ה at the top of letters is a longstanding minhag
and is permissible.
R’ Moshe Feinstein (Igros
Moshe YD 2:138) writes that while he is not overly concerned about the
destruction of such letters, it may not be appropriate to write ב"ה on secular correspondence. R’ Moshe
Sternbuch (Teshuvos
Vehanhagos 1:640) adds that the
Vilna Gaon did not include it in his letters either. Nevertheless, both suggest
that those who wish to begin with a religious expression may instead write בס"ד, which stands for bisyata dishmaya, “with
help from Heaven” (see Aruch Hashulchan YD
276:28).
In conclusion, there are differing customs regarding writing ב"ה at the top of a page. Many Chassidim are particular to do so, others prefer to write בס"ד instead, while some avoid writing anything at all.
