Sayyiduna Abdullah bin Umar (may Allah be pleased with him) narrates: The Noble Prophet (peace and blessings be upon him) said:
“The keys of the unseen are five. No one except Allah knows what the wombs will bring forth (i.e., whether a boy will be born or a girl will be born), and no one except Allah knows what will happen tomorrow.
No one except Allah knows when it will rain. And no person knows on which land he will die. And no person knows when the Hour (Day of Judgment) will be established.”
