(the slave of Asma') During the night of Jam', Asma' got down at Al-Muzdalifa and stood up for
(offering) the prayer and offered the prayer for some time and then asked, "O my son! Has the moon
set?" I replied in the negative and she again prayed for another period and then asked, "Has the moon
set?" I replied, "Yes." So she said that we should set out (for Mina), and we departed and went on till
she threw pebbles at the Jamra (Jamrat-Al-`Aqaba) and then she returned to her dwelling place and
offered the morning prayer. I asked her, "O you! I think we have come (to Mina) early in the night."
She replied, "O my son! Allah's Messenger (ﷺ) gave permission to the women to do so."
