Abdullah bin Umar reported,
The Messenger of Allah ﷺ said, "The keys of the unseen are five, which none knows except Allah. No one knows what will happen tomorrow, no one knows what is in the wombs, no soul knows what it will earn tomorrow, no soul knows in what land it will die, and no one knows when the rain will come."
Azami 416
Sahihعن ابن عمر قال
قال رسول الله ﷺ: مفتاح الغيب خمس لا يعلمها إلا الله: لا يعلم أحد ما يكون في غد، ولا يعلم أحد ما يكون في الأرحام، ولا تعلم نفس ماذا تكسب غدا، وما تدري نفس بأي أرض تموت، وما يدري أحد متى يجيء المطر.
Bukhari narrated it in the chapter on the eclipse (1039), from Muhammad bin Yusuf, who said, Sufyan narrated to us from Abdullah bin Dinar, from Ibn Umar, and he mentioned it. In another narration, from Sulayman bin Bilal, from Abdullah bin Dinar, "and no one knows when the Hour will come except Allah" in place of "and no soul knows what it will earn tomorrow."
