The Messenger of Allah ﷺ said: I have been helped by terror (in the heart of the enemy) ; I have been given words which are concise but comprehensive in meaning; and while I was asleep I was brought the keys of the treasures of the earth which were placed in my hand.
عَنْ رَسُولِ اللَّهِ ﷺ أَنَّهُ قَالَ نُصِرْتُ بِالرُّعْبِ عَلَى الْعَدُوِّ وَأُوتِيتُ جَوَامِعَ الْكَلِمِ وَبَيْنَمَا أَنَا نَائِمٌ أُتِيتُ بِمَفَاتِيحِ خَزَائِنِ الأَرْضِ فَوُضِعَتْ فِي يَدَىَّ
