Ruling on Singling Out the Night and Day of the Fifteenth of Sha'ban for Fasting and Standing in Prayer

Question:
Is there an authentic hadith regarding the virtue of fasting on the fifteenth day of Sha'ban? And is there an authentic hadith regarding the virtue of standing in prayer on that night?

Answer:
No, singling out the day of the fifteenth of Sha'ban for worship, or fasting, or the night of the fifteenth has no basis; rather, it is a religious innovation (bid'ah). The correct opinion among the scholars is that it is a religious innovation (bid'ah), and the hadiths concerning it are weak. All the hadiths regarding the night of the fifteenth of Sha'ban are weak, and some are fabricated; they are not authentic.
