Is it true that the Prophet, peace and blessings be upon him, said: "Whoever visits my brother Yunus is as if he has visited me," and is it permissible to visit the grave of the Prophet Yunus, peace be upon him?

The hadith (definition) "Whoever visits me, and visits my father Abraham and Yunus in one year, will enter Paradise" has not been reported. What has been reported is: "Whoever visits me and visits my father Abraham in one year will enter Paradise," and this is a fabricated, موضوع (forged) hadith. There is no evidence for the definite location of any prophet's grave other than our Prophet Muhammad (peace be upon him). It is permissible to visit the grave of Yunus (peace be upon him) if its location is known and the visit adheres to the Sharia (definition) regulations.
