Uthman offered complete prayer at Mina for the sake of bedouins who attended (hajj) in large numbers that year. He led the people four rak'ahs in prayer in order to teach them that the prayer (i.e. noon or afternoon prayer) essentially contained four rak'ahs.
I prayed along with the Messenger of Allah (ﷺ) at Mina and the people gathered there in large numbers. He led us two rak'ahs in prayer in the Farewell Pilgrimage. Abu Dawud said: Harithah belonged to the tribe of Khuza'ah, and they had their houses in Mecca.
On the authority of his mother: I saw the Messenger of Allah (ﷺ) throwing pebbles at the jamrah from the botton of wadi (valley) while he was riding (on a camel). He was uttering the takbir (Allah is most great) with each pebble. A man behind him was shading him. I asked about the man. They (the people) said: He is al-Fadl b. al-'Abbas. The people crowded. The Prophet (ﷺ) said: 'O people, do not kill each other ; when you throw pebbled at the jamrah, throw small pebbles.
I saw the Messenger of Allah (ﷺ) near the Jamrat al-Aqabah (the third or last pillar) riding (on a camel) and I saw a pebble between his fingers. He threw the pebbles and the people also threw (stones at the Jamrah).
حَدَّثَنَا الْقَعْنَبِيُّ، حَدَّثَنَا عَبْدُ اللَّهِ، - يَعْنِي ابْنَ عُمَرَ - عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، أَنَّهُ كَانَ يَأْتِي الْجِمَارَ فِي الأَيَّامِ الثَّلاَثَةِ بَعْدَ يَوْمِ النَّحْرِ مَاشِيًا ذَاهِبًا وَرَاجِعًا وَيُخْبِرُ أَنَّ النَّبِيَّ صلى الله عليه وسلم كَانَ يَفْعَلُ ذَلِكَ .
Nafi' reported on the authority of Ibn Umar. He (ibn Umar) used to come (to Mina) and threw pebbles three days after the day of sacrifice walking when arriving and returning (both ways). He reported that the Prophet (ﷺ) used to do so.
I saw the Messenger of Allah (ﷺ) throwing pebbles on the day of sacrifice while on his riding beast and saying: Learn your rites, for I do not know whether I am likely to perform Hajj after this occasion.
