Salam alaikum.

It was reported from Anas ibn Malik (may Allah be pleased with him), as if prophet (sallalahu alaihi wa ala alihi wa sallam) said to Ali (may Allah be  pleased with him): You explain to  my nation things that they differ in, after me.

Opinion of scholars:

  • 1) Shaykh Albani said it’s fabrication in “Silsila ahadeth al-mawdoa” #4891.
  • 2) al-Hakim said it’s sahih on the terms of shaykhan in his “Mostadrak”.
  • 3) Dhahabi rejected this opinion of Hakim, and noticed that it’s from fabrications of narrator Dirar, in his “Talkhees”.

We can see this narration along with chain in “Mustadrak”:

4620 – حدثنا عبدان بن يزيد بن يعقوب الدقاق من أصل كتابه ثنا إبراهيم بن الحسين بن ذيزيل ثنا أبو نعيم ضرار بن صرد ثنا معتمر بن سليمان قال : سمعت ابي يذكر عن الحسن عن أنس بن مالك رضي الله عنه أن النبي صلى الله عليه و سلم قال لعلي : أنت تبين لأمتي ما اختلفوا فيه من بعدي

There is no doubt that Hakim erred in his grading, and was extremely lenient in this taskheh. Main problem in narrator Abu Nuaym  Dirar ibn Surad.

Opinion of scholars on this narrator:

  • Bukhari and other said: He’s abandoned (matrook).
  • Yahya ibn Muin said: “There are two liars in Kufah, this one, and Abu Nuaym (Abdurrahman ibn Khani) an-Nakhai”.
  • Nasai said: He’s not truthful (leytha bi thiqat)
  • Abu Khatim said: Saduq, and not to be rely on.
  • Daraqutni said: Weak.    (see “Mizanul itidal” 2/327-328/#3951)

Same narrator also present in chain of such narration in “Mojam ibn al-Arabi”.
