The hadith of ʿUthmān is a good (ḥasan) hadith.¹

The scholars act upon this: they disapproved of the muezzin² taking payment for the adhān, and they recommended that the muezzin seek his reward from Allah (iḥtisāb) in his adhān.

43 – Chapter: What one says of supplication when the muezzin gives the adhān

208 – Qutaybah narrated to us, he said: al-Layth narrated to us, from al-Ḥukaym ibn ʿAbd Allāh ibn Qays, from ʿĀmir ibn Saʿd, from Saʿd ibn Abī Waqqāṣ, from the Messenger of Allah ﷺ, who said: "Whoever says, when he hears the muezzin: 'And I bear witness that there is no god but Allah alone, with no partner, and that Muḥammad is His servant and His Messenger. I am content with Allah as Lord, and with Islam as religion, and with Muḥammad as Prophet and Messenger' — his sins will be forgiven."

= Allah, and they thought he was Ashʿath ibn ʿAbd al-Malik al-Ḥumrānī, the trustworthy narrator, following in that what Ibn Ḥazm stated in his chain in al-Maḥallā 3/145, identifying him as such — and that is an error on his part or on the part of other narrators. However, the hadith has two other authentic chains in Aḥmad (16271), Abū Dāwūd (531), al-Nasāʾī 2/23, and Abū ʿAwānah (1557).

It was also transmitted by al-Ḥumaydī (906), Ibn Abī Shaybah 1/228, Ibn Mājah (714), al-Ṭabarānī (8376) and (8378), Abū Nuʿaym in al-Ḥilyah 8/134, and Ibn Ḥazm in al-Maḥallā 3/145.

¹ In the edition of Shaykh Aḥmad Shākir it appears as "ḥasan ṣaḥīḥ" with the addition of "ṣaḥīḥ," which is not found in any of our manuscript copies, nor in the commentaries of Ibn Sayyid al-Nās and al-Mubārakfūrī, nor is it quoted from him by al-Mizzī in Tuḥfat al-Ashrāf 8/238.

² The word "muezzin" we have established from (L) and the copy of Ibn Sayyid al-Nās, and it is not found in the rest of our manuscript sources.
