What is the ruling on singling out New Year's Eve for prayer and worship, and calling for communal night vigil prayers and worship gatherings?

The Sunnah does not specify New Year's Eve for worship. A Muslim must beware of innovation in religion. The Prophet, peace and blessings be upon him, forbade singling out Friday night for vigil. Attachment to New Year's nights is a custom of disbelievers, and we have been forbidden from imitating them. Inviting people to stay up late and perform night prayers collectively is permissible if the motive is worship and teaching it. However, if the gathering is intended for its own sake, believing it has a special virtue or distinction, then it is not permissible.
