He also states...
He also states, 'and He began the creation of man from clay (32:7)', and the Glorious states, 'There are others, held in suspense for the command of Allah, whether He will punish them, or turn to them in mercy (9:106)'. He, the Glorious, also states, 'Nor is an individual's life prolonged, nor does anything decrease from his life span, except that it is (being reflected) in a Book (35:11)'." Sulaiman asked: "Do you have any narrations from your ancestors on this?" The Imam (AS) replied: "Yes.
It is narrated to me that Abu Abdillah (Imam al-Sadiq (AS)) said, 'Surely for Allah, the Glorious, there are two (types of created) knowledge: One is the hidden and the reserved knowledge (i.e., the knowledge of al-Ghaib) that no one knows but He, and from that comes al-Badaa.

Next, Allah revealed to that Prophet to go back to the king and to inform him that Allah has caused his (previous) appointed time of death to be forgotten (i.e., He has made its decree disappear) and increased his life for 15 years. That Prophet said to Allah, 'O Lord!
