Al-Zarqaani also said about him in Sharh Muwatta Imam Maalik (Vol 1 Pg 321) that Its chain is Da’eef.
From this detail we come to know that Abdur Rahmaan bin Ishaaq is Da’eef and Majrooh according to the Jumhoor of Muhadditheen, some have even called him Mut-ham and Matrook, therefore his narration is Mardood, that’s why Haafidh Ibn Hajar said:
“Its chain is Weak” [Al-Dirayah: 1/168]
Bayhaqi said: “It chain is not proven”
Nawawi said: “This hadeeth is Da’eef with agreement” [Nasb ur-Rayaa: Vol 1 Pg 314]
Though Zayla’ee Hanafi did not refute it, but the Mutassub Footnoters of Nasb ur-Rayaa said that:
“Tirmidhi has graded a hadeeth of Abdur Rahmaan bin Ishaaq as Hassan and Haakim as Saheeh”
Whereas Haakim and Tirmidhi both are famous with Tasahul according to them. Tirmidhi has graded a hadeeth of Katheer bin Abdullah as Saheeh whereas Katheer is even declared to be a Liar, that’s why as said by Haafidh Dhahabi, “The Scholars do not trust the Tasheeh of Tirmidhi” [Mizaan ul-I’tidaal: 3/407]
Haakim has authenticated the hadeeth of Abdur Rahmaan bin Zayd bin Aslam in al-Mustadrak, whereas the same Haakim writes in his book “Al-Madkhal Ila as-Saheeh” that:
“‘Abd al-Rahmaan ibn Zayd ibn Aslam narrated fabricated ahaadeeth from his father, and it is obvious to any competent hadeeth scholar that he is the one to blame for fabricating ahaadeeth.” (Pg 104)
Zayla’ee Hanafi wrote that:
“The Authentication of Haakim is not trusted.” [Nasb ur-Rayaa: 1/344]
Meaning, according to the Hanafis, the authentication of Haakim has no value and it is not trusted.
It should be noted that no Muhaddith or Imam has ever authenticated the hadeeth of Abdur Rahmaan bin Ishaaq containing the words “Under the Navel”, therefore the saying of Imam Nawawi, that it is Da’eef with agreement, is Correct.
Among the teachers of Abdur Rahmaan, Ziyaad bin Zayd is a Majhool. [Taqreeb at-Tahdheeb: 2078]
No one has done the tawtheeq of Nu’maan bin Sa’d except Ibn Hibbaan, and Abdur Rahman is alone in narrating from him. Therefore Haafidh Ibn Hajar said: “Thus Don’t take evidence from his report” [Tahdheeb at-Tahdheeb: 10/405]
Abdur Rahmaan has also narrated from the chain of “From Sayyaar Abi Al-Hakam, From Abu Waail, From Abu Hurayrah…” Imam Abu Dawood said about this chain that: “And it is narrated from Abu Hurayrah and it is not strong” [Sunan Abu Dawood: Vol 1 Pg 480 H. 757]
