The reply is:
“The existence of what has occurred, while events continue, does not entail its ending.”

If it is said:
“We are supposing that they have ended and run their course.”

“If their finitude is assumed, then their finitude follows on that assumption.”

It is also said:

The reply is:
“Granted that this is called an ending. On this assumption, however, they have ended at the endpoint they have reached, not at the earlier end, which has no beginning.”

Thus, these people do not dispute ending in this sense. Rather, they say:
“All past events have ended, elapsed, passed away, and run their course.”

“Neither cut off nor withheld.” [al-Wāqi'ah: 33]

And He says:

“Say, ‘If the sea were ink for the words of my Lord, the sea would be exhausted before the words of my Lord were exhausted, even if We brought the like of it as a supplement.’” [al-Kahf: 109]

As for having no end in the sense of having no beginning, he has offered no proof of its impossibility. For when someone says:
“That which has no end, in the sense that it has no beginning
