Yes. Authentic reports about the Dajjal—the great deceiver known in hadith as the Antichrist—are found in major collections, including Sahih al-Bukhari and Sahih Muslim. They do not form one single narration: each report has its own wording and focus, so a detail should be traced to its source rather than assumed to belong to every account. Several reports below are explicitly graded authentic and establish the central warnings and descriptions.
Authentic reports about the Dajjal appear in major collections
The reports cited here are narrated in Sahih al-Bukhari and/or Sahih Muslim, two major Sunni hadith collections. The material differs from narration to narration: one report describes the Dajjal’s appearance, another warns about his deception, and another gives a specific account associated with Tamim al-Dari. That is why the wording and source of an individual claim matter.
The strongest reports establish the central warning
A report narrated by al-Bukhari and Muslim from Anas ibn Mālik says that every prophet warned his people about the one-eyed liar. It describes the Dajjal as blind in one eye and states that the letters “k”, “f”, and “r” are written between his eyes. This is a specific description in that report, not a reason to treat every detail circulating online as equally established.
Another report narrated by al-Bukhari and Muslim from Abu Hurayrah warns that the Dajjal will bring something resembling Paradise and Hellfire, while what he calls Paradise will actually be Hellfire. The report also compares the warning against him to the warning given by Nūh (Noah) عليه السلام to his people. Together, these narrations establish the seriousness of the trial and the need to distinguish appearance from reality.
Sahih Muslim contains a longer report from An-Nawwās ibn Sam‘ān that gives further details, including the duration of his stay: forty days, with one day like a year, one like a month, one like a week, and the remaining days like ordinary days. It also says that people should estimate the prayers during the unusually long day. The forty-day detail is therefore supported by an authentic report, not merely by a popular retelling.
Check a Dajjal hadith by tracing its wording and source
When you encounter a claim, first look for its exact wording and the narrator named in the report. Then identify the collection in which it appears and check whether a reliable hadith scholar has graded that specific narration. A quote without a collection, narrator, or traceable wording is not enough to establish that the Prophet Muhammad ﷺ said it. The report warning against attributing deliberate lies to him makes careful sourcing especially important.
A practical way to begin is to browse authentic hadiths about the Dajjal by topic, then compare the result with a reliable grading and the report’s context. If you are new to the terminology, this guide explains how hadith authenticity and major collections are understood. Keep the distinction clear: a report may be authentic while a detail added to a social-media summary is not part of its wording.
Read the Tamim al-Dari report in its specific context
The report associated with Tamim al-Dari is a distinct narration about the Dajjal; it should be discussed as that particular account, not blended into every other report or treated as proof of details it does not state. To explore its wording and scholarly discussion, consult the report of Tamim al-Dari about the Dajjal and its scholarly discussion. This helps keep the account in context while separating what the narration says from claims that may be attached to it in retellings.
Frequently Asked Questions
Is the claim that the Dajjal will rule for 40 days based on an authentic hadith?
The authentic report in Sahih Muslim says that he will remain on earth for forty days, not that he will “rule” for forty days. It specifies that the first day will be like a year, the next like a month, the next like a week, and the remaining days like ordinary days.
Authentic reports in Sahih al-Bukhari and Sahih Muslim establish the Dajjal’s trial and give specific descriptions, but each claim must be checked against its own narration. Trace the wording, narrator, collection, and grading before sharing a quote. You can now distinguish well-attested reports from details that still need a source.
