He carries their signs and is the inheritor of all that they stood for and what was revealed upon them. The following article mentions the similarity between Hazrat Sheeth (as) and Imam Mahdi (as).
Hibatullah Sheeth, did not get the permission to reveal his knowledge, as mentioned in a lengthy report quoted in Rauda Kafi from Imam Baqir (as) that he said, “When Hibatullah buried his father, Adam, Qabeel came to him and said: O Hibatullah I saw that my father, Adam did not give as much knowledge as he gifted to you and it is the same knowledge with which your brother, Habeel prayed and his sacrifice was accepted, and that is why I killed him so that he may not have children who could proudly claim to my children that: ‘We are children of one whose sacrifice was accepted and you are the children of one whose sacrifice was not accepted.’ And if you reveal the knowledge that my father has given to you only, I would kill you too like I killed my brother, Habeel.

“The oppressors thought that the Divine Proof is invalid and destroyed. If we had been permitted to speak freely about him all the doubts would be removed.” (Kamaluddin volume 2 page 430)
