The Messenger of Allah ﷺ addressed us while we were at Mina, and our hearing was opened so clearly that we could hear what he said even while we were in our tents. He began teaching them the rites of pilgrimage, and when he reached the matter of the stone-pillars, he held up his two index fingers and said, "With pebbles the size of those used in flicking."Then he ordered the Muhajirun to camp in the front area of the mosque, and ordered the Ansar to camp behind the mosque, and the rest of the people settled after that.
خطبنا رسول الله ﷺ ونحن بمنى ففتحت أسماعنا حتى كنا نسمع ما يقول ونحن في منازلنا فطفق يعلمهم مناسكهم حتى بلغ الجمار فوضع أصبعيه السبابتين ثم قال: بحصى الخذف. ثم أمر المهاجرين فنزلوا في مقدم المسجد، وأمر الأنصار فنزلوا من وراء المسجد، ثم نزل الناس بعد ذلك.
Abu Dawud narrated it (1957) from Musaddad, who said, Abdul-Warith narrated to us, from Humayd Aaraj, from Muhammad bin Ibrahim Taymi, from Abdul-Rahman bin Muaz Taymi, and he mentioned it.Imam Ahmad likewise narrated it (16589) from Abdul-Samad bin Abdul-Warith, from his father, from Humayd, from Muhammad bin Ibrahim Taymi, from Abdul-Rahman bin Muaz Taymi, and he said, "He was one of the companions of the Prophet ﷺ," he said, "The Messenger of Allah ﷺ delivered a sermon to us," and he mentioned the hadith.Ibn Mubarak followed him in that, narrating from Abdul-Warith, and mentioned the same. Bayhaqi narrated it (127/5).But Nasai narrated it (2996) through the route of Ibn Mubarak, and added in it, "from a man among the companions of the Prophet ﷺ," as will come.Maamar differed from him and narrated it from Humayd Aaraj, from Muhammad bin Ibrahim Taymi, from Abdul-Rahman bin Muaz, from a man among the companions of the Prophet ﷺ, who said, "The Prophet ﷺ delivered a sermon to the people at Mina, and settled them in their places, and said, 'Let the Migrants settle here,'" pointing to the right side of the qibla, "'and the Ansar here,'" pointing to the left side of the qibla, "'then let the people settle around them.'" And he mentioned the rest of the hadith. Ahmad narrated it (16588), and from him Abu Dawud (1951), from Abdul-Razzaq, from Maamar, with his chain of transmission.If this is preserved correctly, then the anonymity of the man does no harm, since he is a companion. The correct view is what Abdul-Warith and Ibn Mubarak narrated, without mentioning the unnamed man, and this is what Bayhaqi graded sahih, except that he found fault with it for being disconnected, saying, "They claim that Muhammad bin Ibrahim Taymi did not meet him, and his narration from him is disconnected."That is what he said! But the scholars who deal with disconnected narrations did not mention that his narration from Abdul-Rahman bin Muaz is disconnected. They specified a number of companions from whom he did not hear, and Abdul-Rahman bin Muaz is not among them. So the default is that it is connected until something comes to contradict this.In fact Abu Hatim said, "He did not hear from Jabir nor from Abu Saeed." Hafiz said in Tahdhib, "His hadith from Ayesha is found with Malik and Tirmidhi, who graded it sahih, and Ayesha died before Abu Saeed and Jabir." In this there is an indication that Hafiz was not satisfied with Abu Hatim's statement.And Bayhaqi's statement "they claim" is not explicit in denying that he heard from him. And Allah knows best.
