There is no basis for this hadith in the books of Ahl as-Sunnah; rather it is mentioned only by the Shi‘ah in their books.

What is required of the Muslim is to believe in all the books that were sent down from Allah, may He be exalted. So we believe in general terms in the books of which we do not know the details, without specifying their number, for Allah knows best about that. And we believe in the books that we know, according to what we know of their details from the texts of Revelation. As for the hadith mentioned, it does not have any reliable chain of narration (isnaad).

The Muslim should verify what he tells and narrates, and he should not narrate anything before checking whether it is sound.

The hadith mentioned in the question is not proven to be soundly narrated from the Prophet (blessings and peace of Allah be upon him). We have no need of it, because we have sound reports which give glad tidings of success and triumph for the one whom Allah saved from the worry and stress of this life, and he is content with little and with what is just enough.
