Narrated `Abdullah bin `Umar: The Prophet said, "The keys of the Unseen are five." And then he recited: 'Verily, the knowledge of the Hour is with Allah (alone).' (31.34)

Narrated Ibn `Umar: Allah's Apostle (p.b.u.h) said, "Keys of the unseen knowledge are five which nobody knows but Allah . . . nobody knows what will happen tomorrow; nobody knows what is in the womb; nobody knows what he will gain tomorrow; nobody knows at what place he will die; and nobody knows when it will rain."

Narrated `Abdullah: Allah's Messenger said, "The key of the Unseen are five: Verily with Allah (Alone) is the knowledge of the Hour He sends down the rain and knows what is in the wombs. No soul knows what it will earn tomorrow, and no soul knows in what land it will die. Verily, Allah is All-Knower, All-Aware." (31.34)

Narrated Ibn `Umar: Allah's Messenger said, "The keys of Unseen are five which none knows but Allah: None knows what will happen tomorrow but Allah; none knows what is in the wombs (a male child or a female) but Allah; none knows when it will rain but Allah; none knows at what place one will die; none knows when the Hour will be established but Allah." (See The Qur'an 31:34.")

Narrated Ibn `Umar: The Prophet said, "The keys of the unseen are five and none knows them but Allah: (1) None knows (the sex) 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."
