It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that I heard the Noble Prophet (peace and blessings be upon him) saying: "Let not the Bedouins overpower you regarding the name of your prayer. Remember! Its name is the 'Isha prayer. At that time, they milk their camels (and because of this, they call the 'Isha prayer 'Atamah')."
