Summary points (for those who do not want to read the whole thread or are confused)
1. The tradition from Zayd bin Aqram , as contained in Saheeh Muslim, and authentic as per the condition of Imam Muslim, in every single source i have gone through, is only relayed by Zayd when he first claims that he has grown very old, his time has long gone and his memory has been in decline. I am not claiming to weaken him and place him among the ikhtilat, given that the Sahaba are given a blanket assurance of not only bring truthful and trustworthy in reporting traditions, but also only ever reporting what they believed to be accurate. However, i have never contended Zayd was lying, or had reported what he could not properly remember. Rather, the best explanation for having other authentic expressions not included by Zayd is that in his old age and memory decline, while he reported what he believed to be accurate, he missed out some statements. Is there every a precedent set by the companions? Absolutely, and one can find authentic traditions we can all agree upon where ibn Umar said something, and then had to be corrected by Abu Hurairah or Aisha. While they only reported what they believed to be accurate, the combination of very old age and memory decline may have led to Zayd not reporting what the Prophet (saw) said in his entirety.
2. I know full well that an authentic chain does not necessarily mean the Matn of the text can be taken. The conditions of a Saheeh Hadith are give, and one of the main ones is that the chain is not odd, or has defects, or the like. However, not only do we have authentic chains (one of the prerequisites ) in the Hasan category , scholars who have authenticated them have not pointed out the statements in them that are not accurate. The scholars who have authenticated them and pointed out statements that are not accurate have not mentioned the phrase 'if you hold onto them, you will never go astray'. Not only has Ibn Hajar graded the chain authentic, without criticising it at all or pointing our defects or claiming it contradicts any authentic narration, Shu'ayb al-Arnau't has explicitly authenticated the Matn 'if you hold onto them you will never go astray'
Example:
حديث صحيح دون قوله " وإنهما لن يفترقا حتى يردا علي الحوض "
It is a sahih hadith, with the exception of the statement “And, verily, both shall never separate from each other until they meet me at the Lake-Fount”
I got it from this book: Musnad Ahmad, Annotator Shu'ayb al-Arnaut, and you can find the comments on Volume 3, page 59.
So putting aside the fact al-Arnaut authenticates the Sanad (in other versions where the chain is reliable), he is even willing to authenticate the part 'if you hold onto them you will never go astray'.
We find al-Albani is also not only willing to authenticate the chain when he deems fit, but also the Matn as well , and so not only have the scholars authenticated multiple Hasan chains, they have also verified that the text (other than the past on separating from the Pond) is authentic in its Matn.
"Narrated by Jabir ibn Abdullah: "I saw Allah's Messenger when performing the hajj seated on his she camel Al-Qaswa on the day of Arafah giving an address, and I heard him saying, "O people, I have left among you something of such a nature that if you adhere to it you will not go astray: Allah's Book and my close relatives, my Ahlulbayt (a.s)."
Narrated by Zaid b. Arqam: Allah's Messenger said, "I am leaving among you something of such a nature that if you lay hold of it you will not go astray after I am gone, one part of it being more important than the other: Allah's Book, a rope stretched from Heaven to Earth, and my close relatives, my Ahlulbayt (a.s). These two will not separate from one another till they come down to the reservoir, so consider how you act regarding them after my departure."
Note: Al-Albani comments about both Hadeeth as being Saheeh (Authentic).

3. The claim scholars were lax in authenticating the chain in this case is absolutely untrue. This is a deception that is spread. We know this because al-Albani and al-Arnaut have graded chains they judge as weak as 'Dhai'f' . They are explicit in mentioning when they deem a chain is not reliable and when it is reliable and i have present ample proof of that in the last two pages. So the comments about laxities are to be cast aside. Major Hadith scholars have authenticated the first two traditions as 'Hasan' at the very least. I place their grading above what anyone on an online forum decides to grade it.
Examples:
Jabir ibn Abdullah said, “I saw the Prophet (saw) during his pilgrimage as was on his camel speaking, so I heard him say, “I left you that you must abide by that you will never go astray, the book of Allah (swt) and my Ahlulbayt (a.s).”
Footnote: Sahih li ghayri(authentic due to external evidence), the chain of this narration however is weak, because of Zayd Ibn Al-Hasan he is Qurashi and Al-Anmati.
As you can see, al-Arnaut has not just randomly graded this 'Hasan' out of laxity, but he has been absolutely explicit in first stating that the chain is not authentic. So when he then explicitly claims that the Sanad is 'Hasan' is not being lax, because he has been willing to weaken the chain if he saw fit, as in the example i have given [first post] where he explicitly graded the chain as Hasan.
Brother Hani or anyone else coming and trying to weaken it based on chain has no weight whatsoever, considering al-Arnaut has graded it Hasan, Ibn Hajar has even graded the chain as Saheeh. You can try to weaken the chain, but it has no weight. Perhaps for some your readers here who recognise the problems accepting this tradition will lead to, but not for anyone who wants to perform a fair and objective analysis.
4. Brother Hani and the online TSN team have opted to refute major scholars like al-Albani in their belief of corroboration. I say that in our articles, we discard the views of non-scholars on online forums, and side with men like al-Albani in their judgements. There are times where there chain is obviously weak, but we find both al-Albani and al-Arnaut grading the chain as 'Hasan due to Shawahid'. Shuay'b al'Arnaut also agrees with him in certain cases. Once again, we must emphasise that we will not give any weight to statements made against al-Albani and al-Arnaut.
For example:
حدثنا عبد الله حدثني أبي ثنا بن نمير ثنا عبد الملك بن أبي سليمان عن عطية العوفي عن أبي سعيد الخدري قال قال رسول الله صلى الله عليه و سلم: اني قد تركت فيكم ما ان أخذتم به لن تضلوا بعدي الثقلين أحدهما أكبر من الآخر كتاب الله حبل ممدود من السماء إلى الأرض وعترتي أهل بيتي الا وانهما لن يفترقا حتى يردا على الحوض
There is no doubt the chain above is weak. However , this is another chain al-Albani is willing to grade as Hasan despite being weak in and of itself, through the witnesses.
He says: وهو إسناد حسن في الشواهد. [ Silsilah al-Ahadith al-Sahihah wa Shayhun min Fiqhihah wa Fawaidihah, go to page 357 in the first edition]
Shu'ayb al-Arnaut agrees with him: سنده حسن بالشواهد. [Muhammad b. Ibrahim al-Wazir al-Yamani, al-‘Awasim wa al-Qawasim fi al-Dhabb ‘an Sunnah Abi al-Qasim Volume one, go to page 178]
None of the scholars had mentioned the additional versions contradicting the one in Saheeh Muslim. Many of them graded the the chains as Saheeh, some as Hasan, and some graded other weaker chains as Hasan owing to corroborating witnesses. Furthermore the scholars also accepted the Matn as authentic, and not just the chain. Therefore our problem is now in the T'awil of the tradition, and not establishing the authenticity.
