Revelation would come to the Messenger of Allah ﷺ while he was on his mount, and it would press its neck down to the ground.
إن كان ليوحى إلى رسول الله ﷺ وهو على راحلته، فتضرب بجرانها.
Ahmad narrated it (24868) from Sulayman bin Dawud, who said, "Abdul-Rahman informed us, from Hisham bin Urwa, from his father, from Ayesha," and he mentioned it.Its chain is hasan because of Abdul-Rahman, who is Ibn Abu Zinad, about whom there is disagreement, though his hadith is hasan in corroborations and supporting narrations. And this is one such case.Bayhaqi narrated it in Dalail Nubuwwah (7/53) via Abdul-Rahman bin Abu Zinad, with the wording, "so she would drop onto her throat from the weight of what was being revealed to the Messenger of Allah ﷺ, and his forehead would pour with sweat on a cold day when Allah revealed to him."Hakim graded it sahih (2/505) after narrating it via Mamar from Hisham, adding, "so she could not move, and she recited the words of Allah ," "Indeed, We will cast upon you a heavy word" [Muzzammil 73:5].This is a strong corroboration for Abdul-Rahman bin Abu Zinad.Haythami said in Majma (8/257), "Ahmad narrated it, and its narrators are the narrators of sahih."I say, this is as he said, for Bukhari cited Abdul-Rahman bin Abu Zinad among his suspended narrations, and Muslim cited him in his Sahih. It does no harm that it was narrated from Mamar, from Hisham, from his father, as a mursal report without mentioning Ayesha, for whoever connected it has an addition.As for her saying, "so she would drop on her jiran," the jiran, with the jim vowelled as kasrah, is the underside of the neck, and a camel, when it rests, stretches its neck on the ground.As for what was narrated from Asma bint Yazid, who said, "I was holding the rein of Adba, the she-camel of the Messenger of Allah ﷺ, when Surah Maidah was revealed to him in its entirety, and it nearly broke the camel's upper arm from its weight," this is daif. Imam Ahmad narrated it (27575), and Tabarani in Al-Kabir (24/178), both via Shayban, from Layth, from Shahr bin Hawshab, from Asma bint Yazid, who related the same.In it is Layth, who is Ibn Abu Salim, whose hadith is predominantly daif.Haythami mentioned it in Majma (7/13) and attributed its fault to Shahr bin Hawshab, but attributing the fault to Layth is more fitting, for Shahr bin Hawshab is disputed, though his hadith is hasan when he does not contradict others.The same was narrated from Abdullah bin Amr, narrated by Imam Ahmad (6643). In it is Ibn Lahia, and his teacher Huyayy bin Abdullah, both of whom are daif, and Haythami mentioned it in Majma (7/13) and attributed its fault to Ibn Lahia.It was also narrated from the aunt of Umm Amr bint Abas, narrated by Bayhaqi in Dalail Nubuwwah (7/145), that she said, "My aunt told me that she was traveling with the Messenger of Allah ﷺ when Surah Maidah was revealed to him, and the hoof of his mount Adba broke from the weight of the surah." In it is Umm Amr bint Abas, who is unknown.
