Question:
He says: Honorable Shaykh, may Allah grant you success, if one vows to fast in Rajab because a relative has recovered from an illness, is it permissible to transfer the fasting to another month?
Answer:
It is not permissible to vow to fast in Rajab, because it is a bid'ah (religious innovation); singling out Rajab is a bid'ah. However, some scholars say that one expiates it with the expiation for an oath. If one makes a vow that is not permissible, he does not carry it out, but he expiates it with the expiation for an oath.
