Do I need to check a hadith before sharing it online?

Why it's so serious

The Prophet ﷺ said that whoever deliberately lies about him should take his seat in the Fire (Sahih al-Bukhari 110). He also said, "Convey from me, even one verse," in the same hadith that repeats this warning (Sahih al-Bukhari 3461). So sharing his teachings is rewarded, but only when what you share is really from him.

If you share something you didn't check and it turns out to be fake, you've helped put words in the Prophet's ﷺ mouth, even without meaning to.

A quick guide to hadith grades

• Sahih (authentic): reliable, with a strong chain of narrators.
• Hasan (good): also accepted, slightly less strong.
• Da'if (weak): doubtful. Some scholars allow mentioning weak hadith about virtues if you note it's weak; many prefer to avoid them.
• Mawdu' (fabricated): made up. Never share it as a hadith.

For example, "Seek knowledge even in China" is widely shared, but hadith scholars consider it very weak or fabricated.

How to check

• Look for a reference: a real hadith usually comes with a collection and number, such as Sahih al-Bukhari 1.
• Search a trusted database: sites like sunnah.com show the text, source and often the grade.
• Ask someone knowledgeable: your local imam or a qualified teacher.
• Be wary of chain messages: "Share this with 10 people and you'll get good news" is a red flag.

If you can't verify it

Don't share it as a hadith. If the meaning is good, you can say it in your own words without attributing it to the Prophet ﷺ, or share a Quran verse or an authentic hadith with the same message instead. The same care applies to all news. See Is it a sin to share fake news online as a Muslim?
