Sahih Muslim Book 16, Hadith Number 4162.
Chapter : The (cases of) bloodshed would be decided first of all on the day of judgment.
Abu Bakra reported that when it was the day of (Dhu’l-Hijja) Allah’s Apostle (may peace be upon him) mounted the camel and addressed and a person had been holding its nose-string. The rest of the hadith is the same.
