Sayyidah Aishah (may Allah be pleased with her) said: It was said: O Messenger of Allah (peace and blessings be upon him)! Shall we not build for you (peace and blessings be upon him) a building at Mina to give you shade? He (peace and blessings be upon him) said: "No! Mina is a place to kneel the camels for whoever arrives first."
