صحيح البخاري#1039Sahihحَدَّثَنَا مُحَمَّدُ بْنُ يُوسُفَ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ عَبْدِ اللَّهِ بْنِ دِينَارٍ، عَنِ ابْنِ عُمَرَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مِفْتَاحُ الْغَيْبِ خَمْسٌ لاَ يَعْلَمُهَا إِلاَّ اللَّهُ لاَ يَعْلَمُ أَحَدٌ مَا يَكُونُ فِي غَدٍ، وَلاَ يَعْلَمُ أَحَدٌ مَا يَكُونُ فِي الأَرْحَامِ، وَلاَ تَعْلَمُ نَفْسٌ مَاذَا تَكْسِبُ غَدًا، وَمَا تَدْرِي نَفْسٌ بِأَىِّ أَرْضٍ تَمُوتُ، وَمَا يَدْرِي أَحَدٌ مَتَى يَجِيءُ الْمَطَرُ ".
Narrated Ibn `Umar:Allah's Messenger (ﷺ) said, "Keys of the unseen knowledge are five which nobody knows but Allah . . . nobody knows what will happen tomorrow; nobody knows what is in the womb; nobody knows what he will gain tomorrow; nobody knows at what place he will die; and nobody knows when it will rain
Scholarly Authentication
The label above is the grade most of these scholars gave — one dissenting opinion no longer speaks for all of them. If any scholar calls a narration fabricated, that verdict is shown instead, whatever the others say. Each scholar's own wording:
Every narration in Sahih al-Bukhari is accepted as Sahih (authentic) by the established status of the book.
