One of the primary evidences used by Hanafis against the practice of raf'ul yadayn before and after ruku' is the hadith in Sahih Muslim related by Tamim bin Tarafa from the companion Jabir bin Samura:
The Messenger of Allah
came out to us while we were raising hands in prayer, upon which he said, "What is the matter with them, raising their hands in prayer as if they are tails of agitated horses
? Be tranquil in prayer." (Sahih Muslim)
Their opponents clarify that this was actually when they were raising hands while saying the final salams in prayer, because there is another hadith related by 'Ubaydillah bin al-Qibtiyya from the same companion Jabir bin Samura:
While we prayed with the Messenger of Allah
we said, "Assalmu alaykum wa rahmatullah" "Assalmu alaykum wa rahmatullah" [and he motioned with his hand to the sides], thereupon the Messenger of Allah
said, "Why are you motioning with your hands as if they are tails of agitated horses?
It is enough for one of you to place his hand on his thigh, and then say salam to his brother on his right and left." (Sahih Muslim)
The Hanafis, however, insist that the two hadiths are different, and that the Prophet said this on two different occasions. In any case, they continue to use this hadith as evidence against raf'ul yadayn before and after ruku'.
There are two main problems with the Hanafis using the hadith of Jabir bin Samura for negating raful yadayn before and after ruku':
(1) The Hanafis maintain that it is recommended to raise hands at every takbir in the Eid prayer! Doesn't this action resemble "tails of agitated horses"?! Shouldn't this be also prohibited since raising hands in prayer is prohibited in the hadith?
(2) And this is a big one: The majority of Hanafis admit that the raful yadayn before and after ruku' was once a sunna but was later abrogated (i.e. it became mansukh). That would mean that the Prophet likened an action that was once a sunna to "tails of agitated horses"!!! Is it permissible to use such words for a sunna even if it was later abrogated? And why would the Prophet use such harsh words for people raising hands only because they thought it was still a sunna and didn't know it was abrogated?
There are two escapes for the Hanafis from this dilemma. One is easier than the other:
(1) The easier one: Stop using this hadith as evidence against raf'ul yadayn before and after ruku'. This will solve the problem but they'll lose one of their main evidences against raf'ul yadayn before and after ruku'.
(2) The hard one: If must use this hadith, then stop raising hands at every takbir in the Eid prayer, and deny that raf'ul yadayn before and after ruku' was ever a sunna (i.e. the Prophet never practiced raf'ul yadayn before and after ruku'). And this is impossible since it has been established by sahih, mutawatir hadiths that he did that. And what about the many companions and many, many early scholars who also did it?
The choice is theirs to make, and Allah knows best.
