Sahih al-Bukhari, Book 56, Hadith 170 (In-Book)

Narrated `Abdullah bin Zaid: that in the time (of the battle) of Al-Harra a person came to him and said, "Ibn Hanzala is taking the pledge of allegiance from the people for death." He said, "I will never give a pledge of allegiance for such a thing to anyone after Allah's Messenger."

حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا وُهَيْبٌ، حَدَّثَنَا عَمْرُو بْنُ يَحْيَى، عَنْ عَبَّادِ بْنِ تَمِيمٍ، عَنْ عَبْدِ اللَّهِ بْنِ زَيْدٍ ـ رضى الله عنه ـ قَالَ لَمَّا كَانَ زَمَنَ الْحَرَّةِ أَتَاهُ آتٍ فَقَالَ لَهُ إِنَّ ابْنَ حَنْظَلَةَ يُبَايِعُ النَّاسَ عَلَى الْمَوْتِ‏.‏ فَقَالَ لاَ أُبَايِعُ عَلَى هَذَا أَحَدًا بَعْدَ رَسُولِ اللَّهِ صلى الله عليه وسلم‏.‏
