Allah is everlasting, Allah is Al-Baqi.
Indeed, we have believed in our Lord that He may forgive us our sins and what you compelled us [to do] of magic. And Allah is better and more enduring.“ 20:73
As humans, the concept of infinity and everlasting, although we know its meaning, cannot be fully understood because everything on this earth has its appointed time. On that day that the horn will blow, everyone will pass away but Allah will remain. Allah will never come to an end as he has no beginning. Time is of no relevance to Allah, Allah created time. All of creation is brought to life, lives and dies. Anything that has been created will come to an end, except for the one who created all of creation, Allah, Al-Baqi.
This name is hard to elaborate on because our minds cannot go past what we know and there is nothing that we know equivalent to Allah. We have understanding of the created but Allah is not created, he is the creator.
The Everlasting, The Eternal, The Ever-Enduring, The Ever-Present
The One who has always existed and who will never cease to be. The One whose existence has neither beginning nor end. The One whose existence is beyond the realm of time.
The One who existed before all of creation, and who will remain after all of this creation has come and gone.
The One who is everlasting, perpetual, beginning-less, endless. The One whose existence is eternal. The One who remains forever, unaffected by time.
From the root b-q-y which has the following classical Arabic connotations:
to remain, continue, endure
to be permanent, everlasting, constant
to survive forever
to be incessant, continuous, endless
The term Bāqī is not specifically used as a Beautiful Name in the Qur'ān.
The term Abqā, also from the b-q-y root, is used in the Qur'ān (20:73) where it is commonly translated as the Most Lasting, Ever Lasting or Most Abiding.
The term baqiyyah is used in the Qur'ān (11:116) to describe persons of excellence, those who possess spiritual understanding and inner discrimination, those who possess a quality of attending to that which is eternal.
Wallahu ta’alaa ‘alem.
And Allah knows Best.
