“Abu Dawud narrated it from Shahr, on the authority of Ibn Amr; and al-Hakim from Abu Hurayrah, on the authority of the Prophet. He said: ‘It is authentic according to the criteria of the two Shaykhs.’ That is what he said!”
You have already seen the hidden defect in its chain of transmission, and that it may serve as supporting evidence. Perhaps for this reason Shaykh al-Islam Ibn Taymiyyah was categorical in attributing it to the Prophet, peace and blessings be upon him, in more than one place in his Fatawa.
