What is the ruling on using weak hadith as evidence in lessons and sermons?
The religion of Islam is based only on authentic chains of narration. Weak, baseless, and fabricated narrations hold no weight. Some preachers knowingly narrate weak hadith for the sake of embellishment, but this is absolutely incorrect.
✔ Imam al-Tirmidhī رحمه الله (279 AH):
“Such a (weak) narration cannot be used as proof.”
(سنن الترمذي, no. 931)
✔ Imam Ibn Khuzaymah رحمه الله (311 AH):
“I have mentioned countless times that I do not deem it permissible to deceive students of knowledge by using weak narrations as evidence. I fear my Creator, the Most Glorious, if I were to deceive students by using weak narrations as proof, even if such narrations seem to support my madhhab.”
(كتاب التوحيد: 2/530)
He also said:
“We (the hadith scholars) do not use mursal or weak reports as proof.”
(كتاب التوحيد: 1/136)
Conclusion:
Weak narrations have no place as proof in lessons, sermons, or religious rulings. Islam is established only upon authentic evidence, and knowingly using weak hadith for preaching is impermissible.
