Have the best names been chosen for the boy (Nibras) and the girl (Ithar)?

The best names are "Abdullah and Abdul Rahman," because the Messenger of Allah, peace and blessings be upon him, said: "Indeed, the most beloved of your names to Allah are Abdullah and Abdul Rahman." It is permissible to be named with any good name, for he, peace and blessings be upon him, said: "Indeed, you will be called on the Day of Resurrection by your names, so make your names good." "Nibras" and "Eethar" are two good names; for Nibras means a lamp, and Eethar means preferring others over oneself. Allah praised the Ansar with the description of Eethar in His saying: "and they give [others] preference over themselves, even though they are in need."
