The Messenger of Allah ﷺ commanded us during the Farewell Pilgrimage to throw pebbles at the Jamarat the size of small stones used for flicking.
أمرنا رسول الله ﷺ أن نرمي الجمار بمثل حصى الخذف في حجة الوداع.
Recorded by Darimi (1939), Ibn Abu Asim in Al-Ahad wal-Mathani (675), and Ibn Qani in Mujam Sahaba (636), all of them through the hadith of Uthman bin Umar, who said, narrated to us Uthman bin Murra, from Abu Salama bin Abdul-Rahman, from Abdul-Rahman bin Uthman Taymi, and he related it.This Abdul-Rahman is the nephew of Talha bin Ubaydullah, that is, he is Abdul-Rahman bin Uthman bin Ubaydullah, the companion, who is well known. He was among those who embraced Islam at the conquest, and his first military expedition was the Umrat al-Qada.Its chain is hasan because of Uthman bin Murra, for his hadith is hasan. In the old printed copy of Darimi's book there occurs an addition, "from his father," which is an error, since the hadith belongs to the musnad of Abdul-Rahman bin Uthman. Ibn Hajar likewise mentioned it in Ithaf Mahra (10/621) as part of the musnad of Abdul-Rahman bin Uthman, quoting from Darimi, and he did not point to this addition. It appears, then, that it is a printing error, or else it was found in some copies, and the correct version, as we have established, is without mentioning "his father."Similar in meaning is what was narrated from Harmala bin Amr (who is Abu Abdul-Rahman), who said, "I performed the Farewell Pilgrimage as a young boy in the company of my uncle Sinan bin Sanna. When we stood at Arafat, I saw the Messenger of Allah ﷺ placing one of his fingers upon the other. I said to my uncle, 'What is the Messenger of Allah ﷺ saying?' He said, 'He is saying, "Throw the pebbles at the jamra like the size of pebbles used for flicking."'"This was recorded by Imam Ahmad (19016) from Affan, who said, narrated to us Wahib, who said, narrated to us Abdul-Rahman bin Harmala, from Yahya bin Hind, that he heard Harmala bin Amr say this, and he related it.It was also recorded by Bazzar in Kashf Astar (1131), and Tabarani in Al-Kabir (5/4), and Ibn Khuzayma (2874), all of them through the route of Bishr bin Mufaddal, who said, narrated to us Abdul-Rahman bin Harmala, from Yahya bin Hind, from the father of Harmala bin Amr, who related it with the same chain and similarly.Except that Bishr bin Mufaddal did not name the uncle of Harmala bin Amr, while Wahib did name him, as in the narration of Ahmad. Ibn Khuzayma pointed out that Wahib named Harmala bin Amr's uncle as Sinan bin Sanna.Yahya bin Hind is the son of Asma bin Jariya. Ibn Hibban mentioned him in Al-Thiqat (5/525) and did not mention any narrator from him other than Abdul-Rahman bin Harmala. He said, "This is how Wahib narrated it, from Ibn Harmala, from Yahya bin Hind, from his father (and that is in the hadith of the fast of Ashura). And Abdullah bin Bakr said, from Habib bin Hind, from his father." End of quote.A serious confusion occurred in Al-Tajil, where it says, "Yahya bin Hind bin Asma bin Jariya, from his father and his grandfather, and narrating from him are Sinan bin Sanna and Abdul-Rahman bin Harmala. Ibn Hibban deemed him trustworthy." Then Hafiz critiqued this and clarified what is in Ibn Hibban's Al-Thiqat. He said, "As for Husayni's statement that he narrated from Sinan bin Sanna, I have not seen this in any of the routes of the hadith in the Musnad."The conclusion is that Yahya bin Hind, that is, Yahya bin Hind bin Asma bin Jariya, is majhul (unknown).Haythami said in Al-Majmu (3/258), "Recorded by Ahmad, Bazzar, and Tabarani in Al-Kabir, and its narrators are thiqat (trustworthy)." By thiqat he means merely that Ibn Hibban mentioned them in Al-Thiqat, nothing more.
