Al-Warith
Allah is Al-Warith, The One who remains after all has past. He is everlasting and whom all possessions will be returned to.
From the root w-r-th which has the following classical Arabic connotations: to inherit to be an heir, survivor to be the owner or sustainer after someone.
And indeed, it is We who give life and cause death, and We are the Inheritor. (Quran 15:23)
Indeed, it is We who will inherit the earth and whoever is on it, and to Us they will be returned. (Quran 19:40)
And why do you not spend in the cause of Allah while to Allah belongs the heritage of the heavens and the earth? Not equal among you are those who spent before the conquest [of Makkah] and fought [and those who did so after it]. Those are greater in degree than they who spent afterwards and fought. But to all Allah has promised the best [reward]. And Allah, with what you do, is Acquainted. (Quran 57:10)
