Finality is in Allah's hands

And with Him are the keys of the Ghaib (all that is hidden), none knows them but He. And He knows whatever there is in the land and in the sea; not a leaf falls, but he knows it. There is not a grain in the darkness of the earth nor anything fresh or dry, but is written in a Clear Record.

Al an'aam 59

For every event there is a point (of time and place) to occur, and you will soon know (it).”
Al an'aam 67

It is upto allah that when the azab (calamity/catstrophe) may come from Him

Say (O Muhammad SAW): "I am on clear proof from my Lord (Islâmic Monotheism), but you deny (the truth that has come to me from Allâh). I have not gotten what you are asking for impatiently (the torment). The decision is only for Allâh, He declares the truth, and He is the Best of judges."

Say: "If I had that which you are asking for impatiently (the torment), the matter would have been settled at once between me and you, but Allâh knows best the Zâlimûn (polytheists and wrong¬doers,)."

And with Him are the keys of the Ghaib (all that is hidden), none knows them but He. And He knows whatever there is in the land and in the sea; not a leaf falls, but he knows it. There is not a grain in the darkness of the earth nor anything fresh or dry, but is written in a Clear Record.
