The Messenger of Allah ﷺ said, "The keys of the unseen are five, and none knows them except Allah. None knows what tomorrow will bring except Allah, none knows what the wombs diminish except Allah, none knows when the rain will come except Allah, no soul knows in what land it will die, and none knows when the Hour will come except Allah."
أن رسول الله ﷺ قال: مفاتيح الغيب خمس، لا يعلمها إلا الله: لا يعلم ما في غد إلا الله، ولا يعلم ما تغيض الأرحام إلا الله، ولا يعلم متى يأتي المطر أحد إلا الله، ولا تدري نفس بأي أرض تموت، ولا يعلم متى تقوم الساعة إلا الله.
Bukhari narrated it in the tafsir (4697) from Ibrahim bin Munzir, who said, Maen narrated to us, who said, Malik narrated to me, from Abdullah bin Dinar, from Ibn Umar, and he mentioned it.
