34 - The Book of Oaths and Vows (1)

3761 - Ahmad ibn Sulayman al-Ruhawi and Musa ibn Abd al-Rahman informed us, both saying: Muhammad ibn Bishr narrated to us, saying: Sufyan narrated to us, from Musa ibn Uqbah, from Salim ibn Abd Allah ibn Umar,

from Ibn Umar, who said: There was an oath that the Messenger of Allah, peace and blessings be upon him, used to swear: "No, by the Turner of hearts." (2)

--------------------------------------------
(1) This book appears in "Al-Sunan al-Kubra" divided into two separate books.
(2) Its chain of transmission is authentic. Musa ibn Abd al-Rahman: he is Ibn Sa'id al-Masruqi, and Muhammad ibn Bishr: he is al-Abdi, and Sufyan is Ibn Sa'id al-Thawri. It is in "Al-Sunan al-Kubra" under number (4685).
Ahmad (4788), al-Bukhari (6628), and Ibn Hibban (4332) also narrated it via two paths from Sufyan al-Thawri, with this chain of transmission.
Al-Daraqutni said in "Al-Ilal" 13/103: Ubayd Allah ibn Musa narrated it from al-Thawri, from Musa ibn Uqbah, from Nafi', from Ibn Umar. The correct version is: from Musa ibn Uqbah, from Salim. Al-Hafiz Ibn Hajar said similarly in "Al-Fath" 11/514.
Ahmad (5347), (5368), and (6109), al-Bukhari (6617) and (7391), Abu Dawud (3263), al-Tirmidhi (1540), and the author in "Al-Kubra" (7666) also narrated it via multiple paths from Musa ibn Uqbah, with it.
The aforementioned narration of Abu Dawud appears in "Al-Tuhfah" 5/413 (7024) and 6/246 (8503): from Ubayd Allah ibn Muhammad al-Nufayli, from Ibn al-Mubarak, from Musa ibn Uqbah, from Nafi', from Ibn Umar. Ibn Hajar said in "Al-Fath" 11/514: Al-Nufayli deviated by saying: from Ibn al-Mubarak, from Musa, from Nafi', instead of Salim; Abu Dawud narrated it from the narration of Ibn Dasah.
It will also come with another chain of transmission in the following hadith.
Al-Hafiz said in "Al-Fath" 11/527: What is meant by the "turning of hearts" is the turning of their dispositions and states, not the turning of the heart itself.
