Hadith Grades: Sahih, Hasan, Da'if, and Mawdu'

First PublishedLast UpdatedByCallUponHim.com

You may have heard someone say a hadith is “authentic” or “weak” and wondered what that actually means.

This guide explains how scholars grade hadith, why some well-known sayings are considered unreliable, and how you can check a hadith yourself.

What Is a Hadith?

Section titled “What Is a Hadith?”

A hadith is a report of what the Prophet Muhammad ﷺ said, did, or approved of. Each hadith has two parts:

  • Isnad (chain): the line of people who passed the report down, for example “A heard from B, who heard from C…”
  • Matn (text): the words of the report itself.

When scholars call a hadith “strong” or “weak,” they are not judging whether its message sounds good. They are judging how confident we can be that the report really goes back to the Prophet ﷺ, mainly by examining the chain. The discipline that studies this is called mustalah al-hadith (hadith terminology).

The Main Grades

Section titled “The Main Grades”

1. Sahih (Sound / Authentic)

Section titled “1. Sahih (Sound / Authentic)”

This is the highest grade. Classical scholars list five conditions for a sahih hadith (Masjid Al-Falah; Wikipedia: Sahih Hadith):

  1. An unbroken chain. Every narrator heard it directly from the one before.
  2. Upright narrators. Each is of trustworthy character.
  3. Precise narrators. Each has an accurate memory or accurate written records.
  4. No irregularity (shudhudh). It does not contradict more reliable narrations.
  5. No hidden defect (‘illah). For example, two narrators who lived at the same time but could not actually have met.

2. Hasan (Good)

Section titled “2. Hasan (Good)”

A hasan hadith meets the same conditions as a sahih hadith, except that its narrators’ precision is somewhat lower. Jurists and most hadith scholars still accept it as evidence (SeekersGuidance).

Historically, early scholars used only two categories, sahih and da’if. Al-Tirmidhi was the first to separate out hasan as its own grade (Islamic Awareness).

3. Da’if (Weak)

Section titled “3. Da’if (Weak)”

A da’if hadith is one that fails to meet the conditions of sahih or hasan (SeekersGuidance). Common reasons:

  • a gap in the chain,
  • a narrator known to be unreliable or to have a weak memory,
  • a hidden defect or a contradiction with stronger reports.

A weak hadith is not the same as a false one. It might be genuine, but it cannot be confirmed to the required standard.

4. Mawdu’ (Fabricated)

Section titled “4. Mawdu’ (Fabricated)”

A fabricated report is one falsely attributed to the Prophet ﷺ, for example when the chain includes a known liar (Wikipedia: Categories of Hadith). It is rejected completely and must not be quoted as a hadith, except to warn people about it.

Summary: sahih and hasan narrations are “accepted” (maqbul), and da’if narrations are “rejected” (mardud) as proof (SeekersGuidance).

Grades Can Move Up

Section titled “Grades Can Move Up”

The categories are not rigid boxes. A hasan hadith can be raised to sahih when other chains support it. It is then called sahih li-ghayrihi, meaning “sahih because of external support” (Wikipedia: Hasan).

In the same way, a mildly weak narration reported through several independent routes can rise to hasan li-ghayrihi. A very weak or fabricated narration, however, cannot be strengthened by other chains like it. Classical scholars including al-Tirmidhi, Ibn al-Salah, Ibn Kathir, Ibn Hajar and al-Suyuti agreed on this (3sixtyIslam).

Different scholars sometimes grade the same hadith differently. That is why references often say things like “graded hasan by one scholar, da’if by another.”

Can Weak Hadith Be Used at All?

Section titled “Can Weak Hadith Be Used at All?”

Scholars agree that weak hadith cannot be used to establish belief (aqeedah) or legal rulings (halal and haram).

On using them to encourage good deeds (fada’il al-a’mal), there is a difference of opinion:

  • The majority view. Many scholars permit it. Ibn Hajar al-Asqalani set three conditions (SeekersGuidance; Living Islam):
    1. The hadith must not be very weak. This excludes narrations from liars, those accused of lying, and those who make serious mistakes.
    2. Its content must fall under a principle already established by stronger evidence.
    3. The person acting on it must not firmly believe the Prophet ﷺ said it.
  • A minority view. Some scholars, such as Qadi Abu Bakr ibn al-Arabi al-Maliki, did not allow acting on weak hadith even for virtuous deeds (SeekersGuidance).

Famous Examples That Are Commonly Shared

Section titled “Famous Examples That Are Commonly Shared”

Example 1: “Seek Knowledge, Even If You Have to Go as Far as China”

Section titled “Example 1: “Seek Knowledge, Even If You Have to Go as Far as China””

This is one of the most quoted sayings attributed to the Prophet ﷺ, yet hadith scholars have long judged it unreliable.

Why it was graded down:

  • All of its chains are weak. Al-Bayhaqi noted that the saying is famous but every chain for it is weak (IslamQA – Hanafi).
  • One narrator is the core problem. The chain includes Abu Atikah Tarif ibn Salman. Ibn al-Qaysarani described him as munkar al-hadith jiddan, meaning his reports are severely rejected. That is one of the harshest labels a narrator can receive (IslamQA – Hanafi).
  • Some scholars went further. Ibn Hibban said it is false and has no source, and Ibn al-Jawzi classed it as fabricated (IslamWeb). In modern times, al-Albani also classed it as fabricated in Da’eef al-Jaami’ (IslamQA).
  • Not everyone went that far. A minority of hadith scholars argued that its multiple routes raise it to hasan li-ghayrihi (AskImam). Overall, most scholars consider it weak, and some consider it fabricated.

The authentic core: A related, shorter hadith, “Seeking knowledge is obligatory upon every Muslim,” is narrated by Ibn Majah from Anas ibn Malik and was graded sahih by al-Albani (IslamQA). So the value of seeking knowledge is well supported. It is the “China” wording that cannot be reliably attributed to the Prophet ﷺ.

Example 2: “We Have Returned From the Lesser Jihad to the Greater Jihad”

Section titled “Example 2: “We Have Returned From the Lesser Jihad to the Greater Jihad””

This saying presents struggling against one’s own desires as the “greater jihad.” It is popular in spiritual writing.

Why it was graded down:

  • Ibn Taymiyyah said it has no basis and that no authority on the Prophet’s words and deeds reported it (Yaqeen Institute).
  • Ibn Hajar and al-Albani also challenged its authenticity (Al-Mawrid).
  • A more precise way to put it is that the narration does have a chain, but a flawed one, so “weak” describes it better than “chainless” (Yaqeen Institute).
  • Similar wording is recorded as a saying of Ibrahim ibn Abi ‘Ablah, a Successor (a later generation), rather than of the Prophet ﷺ (Abu Amina Elias).

Note: The idea that struggling against one’s ego matters greatly is supported elsewhere. Al-Tirmidhi records the hadith “The mujahid is the one who strives against his own soul” and grades it hasan sahih (Jami’ at-Tirmidhi 1621 on sunnah.com). The weakness applies to the specific “lesser/greater” wording.

Example 3: “Love of One’s Homeland Is Part of Faith”

Section titled “Example 3: “Love of One’s Homeland Is Part of Faith””

This phrase (hubb al-watan min al-iman) is often quoted as a hadith.

Why it was graded down:

  • Hadith scholars found no chain for it.
  • Imam al-Saghani and Mulla ‘Ali al-Qari classed it as fabricated (HadithAnswers).
  • Al-Sakhawi said he could not find it as a hadith, though he considered its meaning acceptable (HadithAnswers).
  • The Federal Territory Mufti’s Office in Malaysia concluded it is not from the Prophet ﷺ, while noting that loving one’s birthplace is natural. The Prophet ﷺ himself expressed love for Makkah (Mufti WP).

The Pattern to Notice

Section titled “The Pattern to Notice”

In all three examples, a sound or acceptable idea was wrapped in wording that cannot be traced to the Prophet ﷺ. Seeking knowledge, struggling against the ego, and loving one’s home are all supported in other ways. But attributing specific words to the Prophet ﷺ requires a reliable chain, and these sayings don’t have one.

How to Check a Hadith Yourself

Section titled “How to Check a Hadith Yourself”
  1. Look it up on sunnah.com. It lists hadith from the major collections, often with gradings from classical and modern scholars.
  2. Search Dorar.net (Arabic). It gathers gradings from many scholars for a given text.
  3. Check references on weak and fabricated narrations, such as al-Albani’s Silsilat al-Ahadith al-Da’ifa wa al-Mawdu’a. In that work he examined thousands of narrations and explained the reason for each grading (Wikipedia). Classical works like al-Sakhawi’s al-Maqasid al-Hasanah address popular sayings specifically.
  4. Treat a missing source as a red flag. If a widely shared “hadith” comes with no collection name and no grading, be careful before passing it on.
  5. Ask a qualified scholar when gradings conflict or the matter affects practice.
