Musnad Ahmad Hadith 26966

Abdullah, who narrates from Asma’s freed slave, reports that once Asma camped near Muzdalifah and asked, “Son, has the moon set?” It was the night of Muzdalifah and she was praying. I said, “Not yet.” She continued to pray for a while longer, then asked, “Son, has the moon disappeared?” By that time, the moon had set, so I said, “Yes!” She said, “Then depart.” So we left from there, and upon reaching Mina, performed the stoning at Jamrah Aqabah, and after reaching our tent, offered the Fajr prayer. I said to her, “We left Muzdalifah while it was still dark.” She replied, “Not at all, son. The Prophet (peace be upon him) has given women permission to leave early.”
