Abdullah bin Dinar narrates: He heard Sayyiduna Abdullah bin Umar (may Allah be pleased with him) saying: The Prophet Muhammad (peace be upon him) said:

“The keys of the unseen are five. Only Allah knows them. No one except Allah knows what the wombs will bring forth. And no one except Allah knows what will happen tomorrow. No one except Allah knows when it will rain. No person knows in which land he will die. And no one except Allah knows when the Hour (Day of Judgment) will come.”
