Sahih al-Bukhari, Book 96, Hadith 6 (In-Book) ⓘ

Narrated Sa`id bin Al-Musaiyab: Abu Huraira said that Allah's Messenger said, "I have been sent with 'Jawami-al-Kalim ' (the shortest expression with the widest meaning) and have been made victorious with awe (cast in my enemy's hearts), and while I was sleeping, I saw that the keys of the treasures of the world were placed in my hand." Abu Huraira added: Allah's Messenger has gone, and you people are utilizing those treasures, or digging those treasures out." or said a similar sentence.

حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا إِبْرَاهِيمُ بْنُ سَعْدٍ، عَنِ ابْنِ شِهَابٍ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏ "‏ بُعِثْتُ بِجَوَامِعِ الْكَلِمِ، وَنُصِرْتُ بِالرُّعْبِ، وَبَيْنَا أَنَا نَائِمٌ رَأَيْتُنِي أُتِيتُ بِمَفَاتِيحِ خَزَائِنِ الأَرْضِ، فَوُضِعَتْ فِي يَدِي ‏" ‏‏.‏ قَالَ أَبُو هُرَيْرَةَ فَقَدْ ذَهَبَ رَسُولُ اللَّهِ صلى الله عليه وسلم وَأَنْتُمْ تَلْغَثُونَهَا أَوْ تَرْغَثُونَهَا، أَوْ كَلِمَةً تُشْبِهُهَا‏.‏
