The Islamic year of 1434 Hijriyya has now begun, it is well known the traditions of the world in celebrating and congratulating upon the arrival of the new year [AD], however what is the Islamic ruling on congratulations for the new Hijry year?
Shaikh al-Fawzaan, “This is an innovation, congratulating for the new year, it is an innovation; or commanding of fasting or charity [for the purpose of the new year] all of this is innovation, Allah has not revealed evidence upon it”
[Al-Muntaqa min Akhbaar Sayyid al-Mursaleen – 39: via Sahab]
Shaikh ibn ul-Uthaymeen, “If someone congratulates you then reply [i.e. make dua that Allah makes it a good and blessed year], but do not do it yourself [i.e. do not begin it yourself by congratulating someone initially]….I do not know that the Salaf used to congratulate each other for the arrival of the new year of Hijra…”
