It is narrated from Sayyidah Umm Salamah (may Allah be pleased with her); she said: The Messenger of Allah (peace and blessings be upon him) sent me ahead on the night of Muzdalifah along with the weak members of his household. She said: So I stoned the Jamrah during the night, then went on to Makkah and prayed the Fajr prayer there, then returned to Mina.
