What is the ruling on a Muslim supplicating for good for his Muslim brother for the advent of the new Hijri year, intending a general supplication for good and not believing in a specific Sunnah?

There is no religious text that explicitly states whether congratulating people on the Hijri new year is a Sunnah or an innovation. Scholars have differed on this matter: some consider it an act of worship, the default rule for which is divine prohibition unless explicitly permitted, while others treat it as a customary practice. Some view congratulations as permissible, neither a Sunnah nor an innovation, and this is the view of the Malikis. It is among the permissible acts that can become an act of obedience through good intention, due to what it entails in terms of reviving the nation's history and spreading awareness of it among the youth.
