Is performing congregational prayer in the mosque on the night of Al-Israa’ wal-Mi‘raaj, along with Salat Al-Haajah (prayer of need) and Tasbeeh (glorification of God) 100 times, considered part of the Sunnah or an innovation?

It is not prescribed to celebrate the night of Isra and Mi'raj with specific acts of worship, such as the Salat al-Hajah (Prayer of Need) or Tasbih (glorification) with a specific number. This is considered an innovation (bid'ah), similar to committing to particular acts of worship at specific times not designated by Islamic law. Furthermore, there are many differing opinions regarding the exact date of the night of Isra and Mi'raj.
