As-salamu `alaykum wa Rahmatullah Wa Barakatuh. I have noticed that some Muslims specify the 15th of Sha`ban with some acts of worship such as fasting during the dayti me, observing qiaym al-layl or night vigil, reading the Glorious Qur'an, and making du`aa'. Is this right from the Islamic perspective? Please clarify. Jazakum Allah khayran.
