(Imām Bukhārī narrates): Muhammad bin Yusuf narrated the hadith to us, he said: Sufyan narrated the hadith to us, from Abdullah bin Dinar, from Hazrat Ibn Umar (Allāh be pleased with them both), he narrated that the Messenger of Allāh ﷺ said:
There are five keys of the unseen which no one knows except Allāh: No one knows what will happen tomorrow, and no one knows what is in the wombs of mothers, and no one knows what he will do tomorrow, and no one knows in what place on earth he will die, and no one knows when the rain will come.
حَدَّثَنَا مُحَمَّدُ بْنُ يُوسُفَ قَالَ حَدَّثَنَا سُفْيَانُ عَنْ عَبْدِ اللَّهِ بْنِ دِينَارٍ عَنْ ابْنِ عُمَرَ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مِفْتَاحُ الْغَيْبِ خَمْسٌ لَا يَعْلَمُهَا إِلَّا اللَّهُ لَا يَعْلَمُ أَحَدٌ مَا يَكُونُ فِي غَدٍ وَلَا يَعْلَمُ أَحَدٌ مَا يَكُونُ فِي الْأَرْحَامِ وَلَا تَعْلَمُ نَفْسٌ مَاذَا تَكْسِبُ غَدًا وَمَا تَدْرِي نَفْسٌ بِأَيِّ أَرْضٍ تَمُوتُ وَمَا يَدْرِي أَحَدٌ مَتَى يَجِيءُ الْمَطَرُ
