Sayyidah Aishah (may Allah be pleased with her) said that the Prophet (peace and blessings be upon him) sent Umm Salamah (may Allah be pleased with her) on the night of sacrifice; she stoned before dawn, then went back, and that was the day on which the Prophet (peace and blessings be upon him) would be with her.
