Sayyiduna Jabir (may Allah be pleased with him) says that the Messenger of Allah (peace and blessings be upon him) said: "All of Arafah is a place of standing, all of Muzdalifah is a place of standing, all of Mina is a place of slaughter, and all the mountain paths of Makkah are a road and a place of slaughter."
Ya'qub said: Usamah bin Zayd is, according to the people of his city, Madinah, thiqah (trustworthy) and reliable.
