Hadith 37:66
Ghundar narrated to us, from Shu'bah, from Waqid ibn Muhammad ibn Zayd, that he heard his father narrating from Abdullah ibn Umar, from the Prophet (may Allah bless him and grant him peace), that he said during the Farewell Pilgrimage: "Woe to you," or he said, "Woe unto you. Do not return after me as disbelievers, striking the necks of one another."
حدثنا غندر عن شعبة عن واقد بن محمد بن زيد أنه سمع أباه يحدث عن عبد الله بن عمر عن النبي صلى الله عليه وسلم أنه قال في حجة الوداع ويحكم أو قال ويلكم لا ترجعوا بعدي كفارا يضرب بعضكم رقاب بعض
