The hadees"if anybody inform about the month of rajab first time,hell is haram for him ,is this hadees swaheeh

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and Messenger.

We not find this Hadeeth in the resources that we have at hand. Nonetheless, another Hadeeth was reported with similar wording but it is about the month of Rabee‘ al-Awwal, and it is a fabricated Hadeeth.

Allaah Knows best.
