Allah is The All-Knower (Al-'Aleem)

Narrated Ibn Umar Radhiyallahu anh:
The Prophet Sallallahu alihiwasalam said, "The keys of the unseen are five and none knows them but Allah: (1) None knows what is in the womb, but Allah: (2) None knows what will happen tomorrow, but Allah; (3) None knows when it will rain, but Allah; (4) None knows where he will die, but Allah (knows that); (5) and none knows when the Hour will be established, but Allah."

Lessons:
- No matter what, we cannot and should not attempt to predict the future. We should not approach sorcerers, astrologists or future tellers also for this. This is Shirk. Man doesnot have knowledge of the Unseen.
- Whenever we plan on doing something, we should always say, "InshAllah"
- We cannot predict what is in the womb- Medicine can say otherwise, but only Allah knows as He is the One who determines the destiny of what is in the womb.
-We cannot predict the time of our death. Death is not dependent upon age or wellness of a person. So, strive to do good always, as Malak-ul-mawth (The Angel of death) can come anytime.
- The last Hour, the end of this world is unknown to us, and we have no right to predict it. We should not have a doubt when scientists try to predict and prove when the last hour will be.

And Allah knows best.
