A: No specific act of Ibadah has been prescribed for the night of 15th of Sha’ban. Besides Taubah (repentance) and abundant Istighfar (seeking forgiveness from Allah Ta’ala), the night should be spent in beneficial acts of worship that one feels comfortable with. Importantly, all acts of sin, innovation and frivolity should be avoided. Seek guidance from your local Ulama.
And Allah Knows Best
