What is the reality of the middle of Sha'ban night, which some Muslims celebrate?

Some Muslims celebrating the middle of Sha'ban, by fasting during its day and praying during its night, is an innovation (bid'ah). This is because no authentic hadith (definition) has been reported concerning it, and because it falls under the legal definition of innovation. Scholars such as Al-Shatibi, Al-Fattani, and Al-Iraqi have stated that the hadiths reported about it are weak or fabricated. They also affirmed that the thousand-rak'ah "Al-Alfiyah" prayer mentioned in connection with it, as well as the six-rak'ah prayer, are innovations that have no sound basis in the Sunnah (definition), and that they are practices of some later Sufis. Most scholars, such as 'Ata', Ibn Abi Mulaykah, the jurists of Medina, the companions of Malik, and Al-Nawawi, have denounced the celebration of this night, emphasizing that it is a reprehensible innovation. Some of them also pointed out that the "Salat al-Bara'ah" (prayer of acquittal) caused great discord, and that its first occurrence was in Jerusalem. As for naming the last days of Sha'ban "Al-Sha'baniyyah" with the purpose of bidding farewell to eating before Ramadan (definition), it has no basis, and some linguists mentioned that its origin is derived from the Christians. In conclusion: There is no celebration or specific act of worship in Sha'ban, neither in its middle nor at its end, and doing so is among the innovations and newly invented matters.
