The Prophet ﷺ said, "The keys of the unseen are five and none knows them but Allah: (1) None knows (the sex) what is in the womb, but Allah: (2) None knows what will happen tomorrow, but Allah; (3) None knows when it will rain, but Allah; (4) None knows where he will die, but Allah (knows that); (5) and none knows when the Hour will be established, but Allah."
عَنِ النَّبِيِّ ﷺ قَالَ مَفَاتِيحُ الْغَيْبِ خَمْسٌ لاَ يَعْلَمُهَا إِلاَّ اللَّهُ لاَ يَعْلَمُ مَا تَغِيضُ الأَرْحَامُ إِلاَّ اللَّهُ وَلاَ يَعْلَمُ مَا فِي غَدٍ إِلاَّ اللَّهُ وَلاَ يَعْلَمُ مَتَى يَأْتِي الْمَطَرُ أَحَدٌ إِلاَّ اللَّهُ وَلاَ تَدْرِي نَفْسٌ بِأَىِّ أَرْضٍ تَمُوتُ إِلاَّ اللَّهُ وَلاَ يَعْلَمُ مَتَى تَقُومُ السَّاعَةُ إِلاَّ اللَّهُ
