Um Salama:
وَعَنِ الزُّهْرِيِّ ، حَدَّثَتْنِي هِنْدُ بِنْتُ الْحَارِثِ ، أَنَّ أُمَّ سَلَمَةَ ، قَالَتِ اسْتَيْقَظَ النَّبِيُّ صلى الله عليه وسلم فَقَالَ " سُبْحَانَ اللَّهِ، مَاذَا أُنْزِلَ مِنَ الْخَزَائِنِ وَمَاذَا أُنْزِلَ مِنَ الْفِتَنِ " .
The Prophet (ﷺ) woke up and said, "Glorified be Allah: What great (how many) treasures have been sent down, and what great (how many ) afflictions have been sent down!"
