Agency in Stoning the Pillars on Behalf of Women

The questioner:
Peace be upon you, and Allah’s mercy and blessings. And you are doing well. Shaykh Abdullah, I performed Hajj with two daughters, and today we stoned the pillars after the crowd had passed and we had reached the area. Knowing that our lodging is near the lodging of the elderly, and I do not have a car, I am walking on foot. Is it valid for me to act as an agent for them?

The Shaykh:
If they are in good health, no, you and they should stone at night in the cool, even after Maghrib, and it is not obligatory to do it during the day. You and they should stone at night in the cool, if they are in good health. But if they are sick, or if there is danger to them due to pregnancy, or if they are very old and frail, there is no harm; they may appoint an agent. And the stoning is not obligatory during the day. If it does not become easy to do it during the time of Dhuhr and Asr, it is stoned after the sun sets. For the previous day, for the day whose sun has set, meaning, not for the day that is coming. For the previous day, yes.
