Third: The defects identified in it by al-Bukhārī, al-Dāraqutnī and others, as discussed above.
Fourth: Even assuming its authenticity, a number of scholars have claimed that it was abrogated. Ibn al-Mundhir (3) said: Some of our colleagues have claimed that placing the hands before the knees was abrogated. This has already been discussed.
Fifth: It accords with the Prophet’s ﷺ prohibition against going down in prayer as a camel does, unlike the hadith of Wā’il ibn Hujr (4).
