Answer:

1. Say: “No one in the heavens and the earth knows the unseen except Allah.” They are not aware of when they will be raised.(Surat an-Naml:65)
2. We tried, as usual, to travel to heaven in search of news but found it filled with fierce guards and meteors. We used to sit there on special seats to listen in. But anyone listening now finds a fiery meteor in wait for him. We have no idea whether evil is intended for those on the earth, or whether their Lord intends them to be rightly guided.(Surat al-Jinn:8-10)
3. Then when We decreed that he (Sulaiman AS) should die, nothing divulged his death to them (jinns) except the worm which ate his staff; so that when he fell down it was made clear to the jinns that if they had truly had knowledge of the unseen they need not have stayed there suffering humiliating punishment. (Surat Saba:14)
4. Say “None in the heavens and the earth knows the Ghaib (unseen) except Allah, nor can they perceive when they shall be resurrected.” [27:65]

Answer:

Truly Allah has knowledge of the Hour and sends down abundant rain and knows what is in the womb. And no self knows what it will earn tomorrow and no self knows in what land it will die. Allah is All-Knowing, All-Aware. (31:34)
