The time of stoning the Pillar of Al-'Aqabah, in its proper Time and making up for it after its Time

Question :

When does the time for stoning the pillar of Al-'Aqabah end and when does the time end for making up for it (i.e., if one missed it)?

Answer:

In reference to stoning the pillar of Al-'Aqabah on the day of the 'Eid, this ends at the entrance of Fajr time on the 11th day and it begins at the end of the night before the day of Sacrifice for the weak and those similar to them who cannot bear the crowding of the people. In reference to stoning it on the days of At-Tashreeq, it is just like stoning the other two pillars along with it. This stoning begins from midday and ends when the Fajr time begins from the night that followed the day (of stoning), unless it is the last of the days of At-Tashreeq (i.e., the 13th). On the last day the stoning ends with the setting of the sun. Along with this, stoning during the day is better. The exception is if during these times, with the large number of Hajj pilgrims, and their roughness, and their lack of concern for each other, if the person fears for himself from death or harm or extreme difficulty, he may stone at night, and there is no sin on him. Likewise, if he stones at night without any fear of this, there is no sin on him. However, it is better that he is mindful of what is safest in this matter and that he does not stone at night unless there is a need to do so. In reference to his statement concerning making up for (missed stoning), it is considered making up for (missed stoning) if it is done after the time of Fajr enters for the following day.
