Messenger of Allah ﷺ said, "The key of the Unseen are five: Verily with Allah (Alone) is the knowledge of the Hour He sends down the rain and knows what is in the wombs. No soul knows what it will earn tomorrow, and no soul knows in what land it will die. Verily, Allah is All-Knower, All-Aware." (31.34) (Using translation from Bukhārī 4627)  

قَالَ رَسُولُ اللهِ ﷺ مَفَاتِحُ الْغَيْبِ خَمْسٌ {إِنَّ اللهَ عِنْدَهُ عِلْمُ السَّاعَةِ وَيُنَزِّلُ الْغَيْثَ} [لقمان 34] وَيَعْلَمُ مَا فِي الْأَرْحَامِ وَمَا تَدْرِي نَفْسٌ مَاذَا تَكْسِبُ غَدًا وَمَا تَدْرِي نَفْسٌ بِأَيِّ أَرْضٍ تَمُوتُ إِنَّ اللهَ عَلِيمٌ خَبِيرٌ
