Verses 10:101-104 of the Noble Quran give the question of this article and talk about it.
The meanings of the verses 10:101-104

Verse 10:101 says:
Say to them, O Muhammad: Behold what is in the heavens: the sun, the moon and the stars; and what is in the earth: the trees, beasts, mountains and oceans! These are all signs for you.
But these signs and the revelations, the warnings and the messengers do not avail those who will not believe, as it is in Allah's foreknowledge.

Verse 10:102 says:
Is there any sign left for them to believe?
What do they await or expect, when they deny you O Muhammad?
Save the like of the days of those who passed away except the punishment of those who passed away (before them) among the disbelievers
Save the like of the days of those who passed away before them? Of communities, that is, the like of chastisements that befell them.
Say: ‘Then await, this: I shall indeed be with you among the waiting'.
Say O Muhammad: Expect then! The descent of punishment and my own destruction! I am with you among the expectant of the descent of punishment and destruction upon you.

Verse 10:103 says:
Then Allah shall save his messengers and the believers in these messengers after the destruction of their people; in like manner as of old, thus. It is incumbent upon Allah to save believers with their messengers. It is incumbent upon Allah to deliver the believers, the Prophet (s) and his Companions, when the time comes for chastising the disbelievers.

Verse 10:104 says:
Say O Muhammad: O mankind! If you are in doubt of my religion, Islam, and whether it is true, then know that I worship not those whom you worship, those upon whom you call instead of Allah, but I worship Allah who one day will cause you to die. He is Allah who takes away your souls and brings you back to life after He makes you die, I worship Allah Who will take you to Him; Who will seize your souls, and I have been commanded to be of the believers with the believers, following their faith.
