Darussalam
[Its chain is daif] and Busiri graded it daif. Abdul-Malik and his teacher are both daif according to the majority. It also appears in Hakim, 3/83, where he graded it sahih according to the standard of the two Shaykhs, and Dhahabi agreed with him. So the hadith is sahih, a sahih corroborating witness, apart from his statement "specifically."
