The beginning and end of stoning the pillars and what is related to it

Question: When does the pilgrim begin stoning the pillars? What is the method of stoning? What is the number of pebbles? With which pillar does the stoning begin? And when does it end?

Answer: He stones the first pillar on the Day of Sacrifice, which is the pillar closest to Makkah, and it is called the Pillar of 'Aqabah. He stones it on the Day of Sacrifice. If he stones it in the latter half of the night of the Day of Sacrifice, that suffices, but it is better that he stone it in the late morning. He continues until the sun sets. If he misses the stoning, he stones it after the sun sets at night, on behalf of the Day of Sacrifice. He stones it one pebble after another, and he says Allahu Akbar with each pebble.
As for the days of Tashreeq, he stones them after the sun has passed its zenith. He stones the first one, which is next to the Musjid al-Khaif, with seven pebbles, saying Allahu Akbar with each pebble. Then he stones the middle one with seven pebbles, and then the last one with seven pebbles, on the eleventh and twelfth days, and likewise on the thirteenth day for those who do not hasten to leave.
The Sunnah is to stand after the first and after the second. After he stones the first, he stands facing the qiblah, with it on his left, and he supplicates to his Lord for a long time. After the second, he stands with it on his right, facing the qiblah, and he supplicates to his Lord for a long time, on the eleventh and twelfth days, and on the thirteenth day for those who do not hasten to leave.
As for the last pillar, which is closest to Makkah, he stones it and does not stand beside it; because the Messenger of Allah (peace and blessings be upon him) stoned it and did not stand beside it, may peace and blessings be upon him.
