from Isḥāq al-Azraq, from al-Aʿmash.
Al-Aʿmash sought out and recorded knowledge in Kūfa several years before the death of ʿAbdullāh ibn Abī Awfā while staying with him in his own town, so I do not think it far-fetched that he actually heard ḥadīths from him.
I read these seven reports to Isḥāq ibn al-Naḥḥās. Ibn Khalīl has informed you; Abū al-Makārim … narrated them, and, among his most elevated transmissions, is the following:
ʿAbd al-Raḥmān ibn Muḥammad, al-Musallam ibn ʿAllān, and Aḥmad ibn ʿAbd al-Salām gave us authorization, saying:
ʿUmar ibn Muḥammad narrated to us; Hibat Allāh ibn Muḥammad narrated to us; Muḥammad ibn Muḥammad ibn Ghailān narrated to us; Abū Bakr al-Shāfiʿī narrated to us; Muḥammad ibn Sulaymān al-Wāsiṭī and Muḥammad ibn Khālid ibn Yazīd al-Ājurrī narrated to us, and they said:
Abū Nuʿaym reported to us; al-Aʿmash narrated to us, from Abū Ṣāliḥ, from Abū Hurayrah, who said:
The Messenger of Allah ﷺ said, “The needy person is not the one who is turned away with a date or two, nor a mouthful or two; rather, the truly needy is he who does not ask people and whose condition is not noticed so that he might be given.” (1)
“Who are you?” – “I am Saʿid ibn Juhman.”
He asked, “What became of your father?” – “The Azariqa killed him.”
He exclaimed, “May Allah curse the Azariqa, may Allah curse the Azariqa! The Messenger of Allah, peace be upon him, told us that they are the dogs of Hell-fire.”
I then said, “The Azariqa alone, or all of the Khawarij?” – “Rather, all of the Khawarij.”
A parallel report from Abu Umama is found in Ahmad, 5/253, through the chain: ʿAbd al-Razzaq → Maʿmar → Abu Ghalib → Abu Umama. Abu Ghalib, Abu Umama’s companion, is a disputed narrator, yet this supporting report may raise the hadith to the level of authenticity.
The hadith is understood to concern the innovative Khawarij who rebelled against ʿAli—see Ibn Hajar as quoted by al-Manawi in Fayd al-Qadir, 3/510.
(1) Chain via al-Aʿmash: recorded by Abu Dawud (1631, Book of Zakat) and Ahmad 2/393. Other chains from Abu Hurayra appear in al-Bukhari (1476, 1479, Book of Zakat; 4539, Tafsir), Muslim (1039, Zakat), al-Nasaʾi 5/85, Malik 2/923 (Description of the Prophet, “What is reported about the needy”), al-Darimi 1/379, and Ahmad 2/260, 316, 395, 445, 457, 469, 506. A route from Ibn Masʿud is in Ahmad 1/384, 446 and in Hilyat al-Awliyaʾ 7/108.
