The ruling on fasting on the fifteenth day of the month of Sha'ban

Question:
He asks about fasting on the fifteenth day of the month of Sha'ban.

Answer:
It is not permissible to single out the fifteenth day for fasting or the night of the fifteenth for standing in prayer. This is a religious innovation (bid'ah) because nothing has been established regarding this from the Prophet (peace and blessings be upon him). His custom was that he would fast, and if it happened to be the night of the fifteenth, there is no harm in that; it would be incidental to his fasting, and he would not single out the night of the fifteenth over any other. Yes.
