It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him) said: "Do not let 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 for this reason, they call the 'Isha prayer 'Atamah)."
