باب غَزْوَةُ الْخَنْدَقِ وَهْىَ الأَحْزَابُ
Sahih al-Bukhari 4105

Narrated Ibn `Abbas:

The Prophet (ﷺ) said, "I have been made victorious by As-Saba (i.e. an easterly wind) and the Ad nation was destroyed by Ad-Dabur (i.e. a westerly wind).

حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ، عَنْ شُعْبَةَ، قَالَ حَدَّثَنِي الْحَكَمُ، عَنْ مُجَاهِدٍ، عَنِ ابْنِ عَبَّاسٍ ـ رَضِيَ الله عنهما ـ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏ "‏ نُصِرْتُ بِالصَّبَا وَأُهْلِكَتْ عَادٌ بِالدَّبُورِ ‏"‏‏.‏
