البخاري:٤٧٧٨حَدَّثَنَا يَحْيَى بْنُ سُلَيْمَانَ قَالَ حَدَّثَنِي ابْنُ وَهْبٍ قَالَ حَدَّثَنِي عُمَرُ بْنُ مُحَمَّدِ بْنِ زَيْدِ بْنِ عَبْدِ اللَّهِ بْنِ عُمَرَ أَنَّ أَبَاهُ حَدَّثَهُ أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ ؓ قَالَ

قَالَ النَّبِيُّ ﷺ مَفَاتِيحُ الْغَيْبِ خَمْسٌ ثُمَّ قَرَأَ {إِنَّ اللَّهَ عِنْدَهُ عِلْمُ السَّاعَةِ}
