[Its chain is daif] Bayhaqi (10/346) transmitted it through Ibn Abu Sabra, from him, and he said, Abu Bakr bin Abu Sabra is daif and cannot be relied upon, except that it has also been narrated from others besides him, from Husayn, with this wording. Ibn Saad (8/215), Bayhaqi, and others also transmitted it through various routes from Husayn, from him. See hadith no. 1628 regarding his status. The hadith also has another route, which is daif, and whoever graded it sahih was mistaken.
