On the authority of Abu Wahb al-Jushami — and he had companionship [with the Prophet] — who said: The Messenger of Allah, peace and blessings be upon him, said: "Keep horses tied up, wipe their forelocks and their hindquarters — or he said: their rumps — and put pendants on them, but do not put bowstrings on them."(1)

49 - Chapter on hanging bells

2554 - Musaddad narrated to us, Yahya narrated to us, on the authority of Ubaydullah, on the authority of Nafi', on the authority of Salim, on the authority of Abu al-Jarrah, the freed slave of Umm Habibah, on the authority of Umm Habibah, on the authority of the Prophet, peace and blessings be upon him, who said: "Angels do not accompany a caravan in which there is a bell."(2)

--------------------------------------------
(1) Its chain is weak due to the unknown status of Uqayl ibn Shabib; al-Dhahabi said of him in "al-Mizan": He is unknown.
It was also recorded by al-Nasa'i (3565) via the chain of Hisham ibn Sa'id al-Taliqani, with this chain.
It is in "Musnad Ahmad" (19032).
Al-Khattabi said: His statement "do not put bowstrings on it" may mean the bowstring itself specifically, rather than other straps, threads, and the like. And it was said: Its meaning is: do not seek vengeance and blood-recompense upon them, and do not race them in pursuit of retaliation, as was their custom in the pre-Islamic era.
(2) Sahih due to corroborating evidence, and this chain is good as a supporting witness. Abu al-Jarrah, the freed slave of Umm Habibah, wife of the Prophet, peace and blessings be upon him, two narrators reported from him, and Ibn Hibban mentioned him in "al-Thiqat." Al-Ijli said: A trustworthy follower [of the Companions]. Al-Dhahabi declared him trustworthy in "al-Kashif," but he said in "al-Mizan": Declared trustworthy — and this is an expression he uses for someone mentioned in Ibn Hibban's "al-Thiqat" whose trustworthiness was not reported from anyone else, so this is more accurate than what came in "al-Kashif."
It was also recorded by al-Nasa'i in "al-Kubra" (8760) via the chain of Malik, from Nafi', with it, and its wording is: "A beast of burden that has a bell is not accompanied by angels."
It is in "Musnad Ahmad" (26770), and "Sahih Ibn Hibban" (4705). =
