Sahih al-Bukhari, Hadith 7340 ⓘ
Narrated Anas: The Prophet brought the Ansar and the Quarish people into alliance in my house at Medina, and he invoked Allah for one month against the tribe of Bani Sulaim in (the last rak`a of each compulsory) prayer.
حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا عَبَّادُ بْنُ عَبَّادٍ، حَدَّثَنَا عَاصِمٌ الأَحْوَلُ، عَنْ أَنَسٍ، قَالَ حَالَفَ النَّبِيُّ صلى الله عليه وسلم بَيْنَ الأَنْصَارِ وَقُرَيْشٍ فِي دَارِي الَّتِي بِالْمَدِينَةِ. وَقَنَتَ شَهْرًا يَدْعُو عَلَى أَحْيَاءٍ مِنْ بَنِي سُلَيْمٍ
