Al-Khatib transmitted it in al-Tarikh (8/49), in the biographical entry of this al-Husayn. He related from Abu Urwah al-Harrani that he said of him:
“We wrote down hadiths from him, but then we became uncertain about his standing. Objectionable hadiths appeared in his books, so our companions abandoned his hadith.”
Al-Dhahabi summarized this in al-Mizan, saying:
“Abu Urwah and others said: ‘Abandoned.’”
Al-Hafiz commented immediately afterward:
“The ‘others’ refers to al-Azdi.”
I say: Thus he—that is, al-Husayn—is not someone whose reports can lend support.
However, the following statement of the Prophet, peace and blessings be upon him, supports this hadith and adds to its strength:
“Allah has prescribed excellence in all things. So, when you kill, kill well; and when you slaughter, slaughter well. Let each of you sharpen his blade and spare his slaughtered animal suffering.”
It was transmitted by Muslim, Ibn al-Jarud, Ibn Hibban, the compilers of the Sunan, and others. It is documented in Irwa al-Ghalil (7/293).
And his statement, peace and blessings be upon him:
“Do you want to make it die several deaths?! Why did you not sharpen your blade before laying it down?”
Al-Hakim transmitted it and declared it authentic, and al-Dhahabi agreed with him. It is as they said, and it is documented in al-Sahihah, no. 24.
