Salam alaikum, at one popular shia site I seen this short article. It’s entitled “Imam Ali (as) and Uthman followed DIFFERENT religions!”.

After such designing heading, rafidi wrote:

There is an interesting narration in Musnaf Abdur-Razzak 11/453, Hadith No. 20983:

أخبرنا عبد الرزاق عن معمر عن بن طاووس عن أبيه قال دخل بن عباس على معاوية فقال له إني لأراك على ملة بن ابي طالب فقال بن عباس لا ولا على ملة بن عفان
Abdur-Razzak – Mu’amar – Ibn Tawus – his father, who said: Ibn Abbas entered upon Mu’awiyah, and Mu’awiyah said to him: “I see you practising the religion of Ibn Abi Talib (i.e. Imam Ali)”. Ibn Abbas answered: “No, I do not practise the religion of Ibn Affan (i.e. Uthman)!

This is quite shocking. Isn’t it? And sadly, all the narrators are narrators of BOTH Sahih al-Bukhari and Sahih Muslim!
So, the religion of Imam Ali (as) was different from that of Uthman and Mu’awiyah?

First of all, rafidi gave wrong translation.

Moawiya asked:

إني لأراك على ملة بن ابي طالب

I see you upon nation (millat) of ibn Abu Talib.

And ibn Abbas answered:

لا ولا على ملة بن عفان

“No, and (I am) not upon nation of ibn Affan”.

Second, exactly in accordance to tradition of his forefathers, rafidi cut text of hadith.

Here hadith in complete form:

20983 – أخبرنا عبد الرزاق عن معمر عن بن طاووس عن أبيه قال دخل بن عباس على معاوية فقال له إني لأراك على ملة بن ابي طالب فقال بن عباس لا ولا على ملة بن عفان قال طاووس يعني ملة محمد صلى الله عليه و سلم ليست لأحد

He cut red marked part, where written: Tawos (one of the narrators) said: “It’s mean nation (religion) of Muhammad sallahu alaihi wa sallam, doesn’t belong to one”.

By such answer, ibn Abbas showed that it’s incorrect to ascribe nation (religion) to anyone except Muhammad (sallalahu alaihi wa ala alihi wa sallam), people could err, moslems could fight against each other, but their religion would remain the same, the one and only, religion of beloved prophet Muhammad (sallalahu alaihi wa ala alihi wa sallam).

Allah knows best.
