Sahih al-Bukhari 29:12
Narrated Usama:
Once the Prophet (ﷺ) stood at the top of a (looked out from upon one) castle amongst the castles (or the high buildings) of Medina and said, "Do you see what I see? (No doubt) I see the spots where afflictions will take place among your houses (and these afflictions will be) as numerous as the spots where raindrops fall."

حَدَّثَنَا عَلِيٌّ، حَدَّثَنَا سُفْيَانُ، حَدَّثَنَا ابْنُ شِهَابٍ، قَالَ أَخْبَرَنِي عُرْوَةُ، سَمِعْتُ أُسَامَةَ ـ رضى الله عنه ـ قَالَ أَشْرَفَ النَّبِيُّ صلى الله عليه وسلم عَلَى أُطُمٍ مِنْ آطَامِ الْمَدِينَةِ فَقَالَ " هَلْ تَرَوْنَ مَا أَرَى إِنِّي لأَرَى مَوَاقِعَ الْفِتَنِ خِلاَلَ بُيُوتِكُمْ كَمَوَاقِعِ الْقَطْرِ ". تَابَعَهُ مَعْمَرٌ وَسُلَيْمَانُ بْنُ كَثِيرٍ عَنِ الزُّهْرِيِّ.
