The old man and the old woman who are unable to fast. And Sirma came, having worked his day. And he related the hadith. (1)

29 - Chapter on the Iqamah

508 - Sulayman ibn Harb and 'Abd al-Rahman ibn al-Mubarak narrated to us, both saying: Hammad narrated to us, from Simak ibn 'Atiyyah (H)

And Musa ibn Isma'il narrated to us, Wahib narrated to us, both from Ayyub, from Abu Qilabah,

from Anas, who said: Bilal was commanded to make the adhan odd (i.e., with an odd number of phrases) and to make the iqamah even (i.e., with an even number of phrases). Hammad added in his narration: "Except the iqamah." (2)

--------------------------------------------
(1) A sound hadith by virtue of its aforementioned witness, though this chain is weak. Al-Mas'udi — namely 'Abd al-Rahman ibn 'Abd Allah ibn 'Utbah — had become confused (in his memory), and Abu Dawud — namely Sulayman ibn Dawud al-Tayalisi — and Yazid ibn Harun both narrated from him after his confusion, and Ibn Abi Layla did not hear from Mu'adh, and there is also disagreement over him regarding its chain.

It is in the Musnad of al-Tayalisi (566), and from his path al-Tahawi extracted it in Sharh Mushkil al-Athar (478).

Ahmad (22124), al-Shashi (1362) and (1363), and al-Tabarani 20/(270) extracted it in full from multiple paths from al-Mas'udi, with this chain.

Al-Tirmidhi (192) extracted it in abbreviated form from the path of Muhammad ibn 'Abd al-Rahman ibn Abi Layla, from 'Amr ibn Murrah, from 'Abd al-Rahman ibn Abi Layla, from 'Abd Allah ibn Zayd, who said: The adhan of the Messenger of Allah, peace and blessings be upon him, was paired, phrase by phrase, in both the adhan and the iqamah. And Ibn Abi Layla (Muhammad) had a poor memory, and 'Abd al-Rahman did not hear from 'Abd Allah ibn Zayd.

See the full discussion of it in Musnad Ahmad (22124).

And see what precedes it.

(2) Its chain is sound. Hammad: he is Ibn Zayd, and Wahib: he is Ibn Khalid, and Ayyub: he is Ibn Abi Tamimah al-Sakhtiyani, and Abu Qilabah: he is 'Abd Allah ibn Zayd al-Jarmi.
