البيهقي:٦٣٨٠ – أَخْبَرَنَا أَبُو عَبْدِ اللهِ الْحَافِظُ وَأَبُو سَعِيدِ بْنُ أَبِي عَمْرٍو قَالَا ثنا أَبُو الْعَبَّاسِ مُحَمَّدُ بْنُ يَعْقُوبَ ثنا أَسِيدُ بْنُ عَاصِمٍ ثنا الْحُسَيْنُ بْنُ حَفْصٍ عَنْ سُفْيَانَ عَنْ حَبِيبٍ يَعْنِي ابْنَ حَسَّانَ عَنِ الشَّعْبِيِّ عَنْ عَلْقَمَةَ قَالَ

قَالَ عَبْدُ اللهِ بْنُ مَسْعُودٍ إِذَا سَمِعْتُمْ هَادًا مِنَ السَّمَاءِ فَافْزَعُوا إِلَى الصَّلَاةِ
