Tirmidhi

Commentary:
Note:
(In the chain of narration, Ruh ibn Junah is extremely weak, rather, he is accused of fabrication.)

Hadith Authentication:
The chain of narration for this report is extremely weak (fabricated).
Its narrator, Rawh ibn Janah al-Dimashqi, has been declared weak and criticized by the majority of hadith scholars.
◄ Hafiz Ibn Hibban said:
«منكر الحديث جدا، يروي عن الثقات ما إذا سمعها الإنسان الذى ليس بالمتبحر فى صناعة الحديث شهد لها بالوضع.»
“He was severely munkar al-hadith (narrated highly objectionable reports); he would narrate such reports from trustworthy narrators that even a person with little expertise in hadith, upon hearing them, would testify that they are fabricated.” [المجروحين 1؍300، دوسرا نسخه 1؍374]
◄ Abu Nu‘aym al-Asbahani said:
“He used to narrate objectionable (munkar) hadiths from Mujahid (the trustworthy Tabi‘i); he is nothing (i.e., not reliable at all).” [كتاب الضعفاء لابي نعيم ص81 ت67]
◄ Hakim al-Naysaburi said:
«روي عن مجاهد أحاديث موضوعة.»
“He narrated fabricated (mawdu‘) hadiths from Mujahid.” [المدخل الي الصحيح ص137 ت59]
↰ This severe criticism and the consensus of the majority prove that Rawh ibn Janah was extremely weak and used to narrate fabricated reports from Mujahid.
↰ It should be noted that the narration of a weak narrator can also be fabricated, provided that the eminent hadith scholars declare it fabricated or there is clear evidence of fabrication. It is not a necessary condition for a fabricated report that its narrator must inevitably be a liar (kadhdhab).
