Question 215: My father, when he was alive, instructed me to give Sadaqah (voluntary charity) as much as I can on the eve of the 15th of Sha‘baan every year. I carried out his will up to now, but some people reproach me for this act. Is Sadaqah given on the eve of 15th of Sha‘baan permissible according to my father’s will or not? Please enlighten us, may Allaah reward you.
Answer: Specifying this Sadaqah for the day of mid-Sha‘baan every year is an impermissible act of Bidd‘ah (innovation in religion), even if this is the will of your father. You have to fulfill this Sadaqah, but without restricting it to the 15th of Sha‘baan; rather, you may give this Sadaqah annually during any month, and it is preferably during Ramadaan... read more here.
Question 214: My question is about the 15th night of Sha`baan. Does the following Aayah (Qur’aanic verse) in Soorah Al-Dukhaan, saying: Therein (that night) is decreed every matter of ordainments. Refer to the 15th night of Sha`baan, or Laylat-ul-Qadr (the Night of Decree), the 27th night of Ramadaan? Is it Mustahab (desirable) during this night to offer worship, engage in Dikr (Remembrance of Allaah), Qiyaam-ul-Layl (optional Night Prayer), recite Qur’aan, and fast the 14th of Sha`baan?
Answer: Firstly, the authentic explanation reported about the night in the Aayah referred to is that it is Laylat-ul-Qadr, not the night of mid-Sha`ban.
Secondly, it is not Mustahab to offer special worship on the night of mid-Sha`baan. It is as ordinary as any other night, and offering special worship on it is a Bidd`ah (innovation in religion)... read more here.
