There is an additional detail in the previously cited account concerning al-Maʾmūn. It says: A man—one of al-Maʾmūn’s own party—set out for Wāsiṭ. He came to Yazīd and said, “The Commander of the Believers conveys his greetings and says to you: I intend to make public the statement, ‘The Qurʾān is created.’” Yazīd replied, “You are lying about the Commander of the Believers; he would never compel people to accept something they do not know.” (1)
The book “Condemnation of Kalām” records the following chain: Muḥammad ibn al-Muntaṣir al-Bāhilī related to us, saying: Muḥammad ibn ʿAbd Allāh al-Ḥusaynī told us; Muḥammad ibn Ibrāhīm al-Ṣarrām narrated to us; Ibrāhīm ibn Isḥāq al-Ghasīlī (2) narrated to us from ʿAbd al-Wahhāb ibn al-Ḥakam, who said: “Al-Maʾmūn used to be asked about Yazīd ibn Hārūn. He would say, ‘He is still alive, and the people were not subjected to any trial until Yazīd passed away.’”
= Ismail ibn Rafiʿ is weak, and so is his teacher, while the two men from the Ansar are unknown. Ibn Kathir reproduced the report in full in his Tafsir 2/146, 149, citing the chain of al-Tabarani: “Ahmad ibn al-Hasan al-Misri al-Ayli (Ibn Hibban and al-Darqutni declared him a liar, and Ibn ʿAdi accused him of stealing hadith) narrated to us; Abu ʿAsim al-Nabil narrated to us; Ismail ibn Rafiʿ, from Muhammad ibn Ziyad, from Muhammad ibn Kaʿb al-Qurazi, from Abu Hurayra…,” and so on.
Ibn Kathir then comments: “This is a well-known hadith, yet it is extremely odd. Parts of it have supporting narrations scattered in other reports, but some of its wording is objectionable. It is transmitted only by Ismail ibn Rafiʿ, the preacher of Madina. Scholars have differed about him: some declared him reliable, others deemed him weak. More than one leading imam—such as Ahmad ibn Hanbal, Abu Hatim al-Razi and ʿAmr ibn ʿAli al-Fallas—explicitly judged his narrations unsound; some even said he should be abandoned. Ibn ʿAdi added: ‘All his hadiths are questionable, though they may be recorded among the weak narrators.’”
The isnad of this report has reached us from him in many divergent forms, which I have collected in a separate booklet. As for its wording, it is exceedingly strange. It is said that he pieced it together from several individual hadiths and presented it as one continuous narration, for which he was criticized.
Al-Suyuti cited it in al-Durr al-manthur 5/339, 342, and further attributed it to ʿAbd ibn Humayd; ʿAli ibn Saʿid in Kitab al-taʿa wa-l-ʿisyan; Abu Yaʿla; Abu al-Hasan al-Qattan in al-Mutawwalat; Ibn al-Munzir; Ibn Abi Hatim; Abu Musa al-Madini (both in al-Mutawwalat); Abu Shaykh in al-ʿIsma; and al-Bayhaqi in al-Baʿth wa-l-nushur.

(2) The nisba refers to Hanzala ibn Abi ʿAmir, “the one washed by the angels.” He was killed at Uhud in a state of major ritual impurity, and the Messenger of Allah ﷺ said: “I see the angels washing him,” hence he was called Hanzala al-Ghasil.
