The Messenger of Allah ﷺ said, "The keys of the unseen are five," then he recited, "Indeed, Allah has knowledge of the Hour, and He sends down the rain, and He knows what is in the wombs. No soul knows what it will earn tomorrow, and no soul knows in which land it will die. Indeed, Allah is Aleem, All-Aware." [Luqman 31:34]
أن رسول الله ﷺ قال: مفاتح الغيب خمس: {إن الله عنده علم الساعة وينزل الغيث ويعلم ما في الأرحام وما تدري نفس ماذا تكسب غدا وما تدري نفس بأي أرض تموت إن الله عليم خبير}
