Sahih Bukhari Volume 9, Book 91, Hadith 7000

حَدَّثَنَا أَحْمَدُ بْنُ الْمِقْدَامِ الْعِجْلِيُّ، حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ الرَّحْمَنِ الطُّفَاوِيُّ، حَدَّثَنَا أَيُّوبُ، عَنْ مُحَمَّدٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ النَّبِيُّ صلى الله عليه وسلم ‏"‏ أُعْطِيتُ مَفَاتِيحَ الْكَلِمِ، وَنُصِرْتُ بِالرُّعْبِ، وَبَيْنَمَا أَنَا نَائِمٌ الْبَارِحَةَ إِذْ أُتِيتُ بِمَفَاتِيحِ خَزَائِنِ الأَرْضِ حَتَّى وُضِعَتْ فِي يَدِي ‏"‏‏.‏ قَالَ أَبُو هُرَيْرَةَ فَذَهَبَ رَسُولُ اللَّهِ صلى الله عليه وسلم وَأَنْتُمْ تَنْتَقِلُونَهَا‏

Narrated By Abu Huraira : The Prophet said, "I have been given the keys of eloquent speech and given victory with awe (cast into the hearts of the enemy), and while I was sleeping last night, the keys of the treasures of the earth were brought to me till they were put in my hand." Abu Huraira added: Allah's Apostle left (this world) and now you people are carrying those treasures from place to place.
