Question: We see some people specifying the 15th of Sha’baan with
particular supplications and reciting the Qur.aan and performing
naafilah prayers. So what is the correct position concerning this,
and may Allaah reward you with good?
Response: That which is correct is that fasting the 15th of Sha’baan
or specifying it with reciting (the Qur.aan) or making (particular)
supplications has no basis. So the day of the 15th of Sha’baan is
like any other 15th day of other months. So from that which is known
is that it has been legislated for a person to fast the 13th, 14th
and 15th of every month, however, Sha’baan is characterised unlike
the other months in that (except for Ramadhaan) the Prophet (sal-
Allaahu alayhe wa sallam) used to fast more in Sha'baan than any other month . So he used to either fast all of Sha'baan or just a little. Therefore, as long as it does not cause difficulty for a person, it is befitting to increase in fasting during Sha'baan in adherence to the example of the Prophet (sal-Allaahu alayhe wa
sallam).

Question: Is standing the night of the 15th of Sha'baan in prayer and
fasting during it's day legislated?
Response: Nothing firm and reliable has been established on the
authority of the Prophet (sal-Allaahu `alayhe wa sallam) that he
stood in prayer in the night and fasted during the day of the 15th of
Sha'baan. So the night of the 15th of Sha'baan is like any other
night, and if someone is a regular worshipper during other nights,
then he may stand the night in prayer on this night without assuming
anything special (because of it being the night of the 15th of
Sha'baan). This is because specifying a time for any act of worship
requires a authentic proof, so if there is no authentic proof then
the act is regarded as an innovation and all innovations are
misguidance. Likewsie, regarding specifically fasting during the 15th
day of Sha'baan, then no (authentic) proof has been established on
the authority of the Prophet (sal-Allaahu `alayhe wa sallam) to
indicate the legislation of fasting on that particular day.
As for that which is mentioned from the ahaadeeth regarding this
subject, then all of it is weak as the people of knowledge have
indicated. However, whoever has the habit of fasting the 13th, 14th
and 15th (of every month), then he can continue and fast during
Sha'baan as he fasts during the other months, without assuming
anything special about the 15th of Sha'baan. Also, the Prophet (sal-
Allaahu `alayhe wa sallam) used to increase in fasting during this
month (Sha'baan), however, he did not particularise the 15th day,
rather proceeded as per norm.
