Narrated Wabra:
I asked Ibn 'Umar (radiallaahu `anhu), "When should I do the Rami of the Jimar?" He replied, "When your leader does that." I asked him again the same question. He replied, "We used to wait till the sun declined and then we would do the Rami (i.e. on the 11th and 12th of Dhul-Hijja)."
Volume 2, Book 26, Number 803:
Narrated 'Abdur-Rahman bin Yazid:
'Abdullah (radiallaahu `anhu) did the Rami from the middle of the valley. So, I said, "O, Abu 'Abdur-Rahman (radiallaahu `anhu)! Some people do the Rami (of the Jamra) from above it (i.e. from the top of the valley)." He said, "By Him except whom none has the right to be worshipped, this is the place from where the one on whom Surat-al-Baqara was revealed (i.e. Allah's Apostle (sallallaahu `alayhi wasallam)) did the Rami."
Volume 2, Book 26, Number 804:
Narrated 'Abdur-Rahman bin Yazid:
When 'Abdullah (radiallaahu `anhu) reached the big Jamra (i.e. Jamrat-ul-Aqaba) he kept the Ka'ba on the left side and Mina on his right side and threw seven pebbles (at the Jamra) and said, "The one on whom Surat-al-Baqara was revealed (i.e. the Prophet (sallallaahu `alayhi wasallam)) had done the Rami similarly."
Volume 2, Book 26, Number 805:
Narrated 'Abdur-Rahman bin Yazid:
I performed Hajj with Ibn Masud (radiallaahu `anhu), and saw him doing Rami of the big Jamra (Jamrat-ul-Aqaba) with seven small pebbles, keeping the Ka'ba on his left side and Mina on his right. He then said, "This is the place where the one on whom Surat-al-Baqara was revealed (i.e. Allah's Apostle (sallallaahu `alayhi wasallam)) stood."
Volume 2, Book 26, Number 806:
Narrated Al-Amash:
I heard Al-Hajjaj saying on the pulpit, "The Sura in which Al-Baqara (the cow) is mentioned and the Sura in which the family of 'Imran is mentioned and the Sura in which the women (An-Nisa) is mentioned." I mentioned this to Ibrahim, and he said, 'Abdur-Rahman bin Yazid told me, 'I was with Ibn Masud (radiallaahu `anhu), when he did the Rami of the Jamrat-ul-Aqaba. He went down the middle of the valley, and when he came near the tree (which was near the Jamra) he stood opposite to it and threw seven small pebbles and said: 'Allahu-Akbar' on throwing every pebble.' Then he said, 'By Him, except Whom none has the right to be worshipped, here (at this place) stood the one on whom Surat-al-Baqra was revealed (i.e. Allah's Apostle (sallallaahu `alayhi wasallam)).' "
Volume 2, Book 26, Number 807:
Narrated Salim:
Ibn 'Umar (radiallaahu `anhu) used to do Rami of the Jamrat-ud-Dunya (the Jamra near to the Khaif mosque) with seven small stones and used to recite Takbir on throwing every pebble. He then would go ahead till he reached the level ground where he would stand facing the Qibla for a long time to invoke (Allah) while raising his hands (while invoking). Then he would do Rami of the Jamrat-ul-Wusta (middle Jamra) and then he would go to the left towards the middle ground, where he would stand facing the Qibla. He would remain standing there for a long period to invoke (Allah) while raising his hands, and would stand there for a long period. Then he would do Rami of the Jamrat-ul-Aqaba from the middle of the valley, but he would not stay by it, and then he would leave and say, "I saw the Prophet (sallallaahu `alayhi wasallam) doing like this."
Volume 2, Book 26, Number 808:
Narrated Salim bin Abdullah:
'Abdullah bin 'Umar (radiallaahu `anhu) used to do Rami of the Jamrat-ud-Dunya with seven small pebbles and used to recite Takbir on throwing each stone. He, then, would proceed further till he reached the level ground, where he would stay for a long time, facing the Qibla to invoke (Allah) while raising his hands. Then he would do Rami of the Jamrat-ul-Wusta similarly and would go to the left towards the level ground, where he would stand for a long time facing the Qibla to invoke (Allah) while raising his hands. Then he would do Rami of the Jamrat-ul-'Aqaba from the middle of the valley, but he would not stay by it. Ibn 'Umar (radiallaahu `anhu) used to say, "I saw Allah's Apostle (sallallaahu `alayhi wasallam) doing like that."
In the description of Hajj on IslamQA, it says:
Then after tawaaf and saa’i, he should go back to Mina and stay there for two night, the 11th and 12th of Dhu’l-Hijjah, and stone the three jamarats during those two days, when the sun has passed its zenith. It is better for him to go to the jamarats walking, but if he rides that is acceptable. He should stone the first jamarah, which is the one that is furthest away from Makkah and next to Masjid al-Kheef, with seven pebbles, one after another, and say “Allaahu akbar” after each throw. Then he should go forward a little and say a lengthy du’aa’, saying whatever he likes. If it is too difficult for him to stand for a long time and make du’aa’, he should say whatever is easy for him, even if it is only a little, so that he will have done the Sunnah.
Then he should stone the middle jamarah with seven pebbles, one after another, saying “Allaahu akbar” with every throw. Then he should move to his left and stand facing the qiblah, raising his hands, and offer a lengthy du’aa’ if he can. Otherwise he should stand for as long as he can. He should not omit to stand and make du’aa’ because it is Sunnah. Many people neglect that because of ignorance or because they take the matter lightly. The more the Sunnah is neglected the more important it becomes to do it and spread it among the people, lest it be abandoned and die out.
Then he should stone Jamarat al-‘Aqabah with seven pebbles, one after another, saying “Allaahu akbar” with each throw, then he should go away and not offer a du’aa’ after that.
When he has completed the stoning of the Jamaraat on the 12th day of Dhu’l-Hijjah, if he wants he may hasten and leave Mina, and if he wants he may delay his departure and stay there for another night, the night of the 13th, and stone the three Jamaraat after noon as he did before. It is better to delay, but it is not obligatory unless the sun has set on the 12th and he is still in Mina, in which case it is obligatory to stay until one has stoned the three Jamaraat after noon on the following day. But if the sun sets on the 12th and he is still in Mina but not by choice, such as if he had already started out and boarded his means of transportation, but got delayed because of crowded conditions and traffic jams etc., then he is not obliged to stay there, because the delay until sunset was not by his choice.
Notice how Ibn Mas`ud is referring to the Prophet (sallallaahu `alayhi wasallam) as the one on whom Surah al-Baqarah was revealed [الَّذِى أُنْزِلَتْ عَلَيْهِ سُورَةُ الْبَقَرَةِ]. It's a nice adjective, don't you think? :)
