Mukhtasar Muslim (Abridged) 225 — Regarding the name of Isha prayer

`Sayyiduna Abdullah bin Umar (may Allah be pleased with them) narrates that` the Messenger of Allah (peace and blessings be upon him) said: "Do not let the Bedouins overpower you regarding the name of the Isha prayer, for in the Book of Allah it is called 'Isha.' They delay the milking of their camels, and that is why they call the Isha prayer 'Atamah.'"
