Hadith 8:2327
Abu Bakr narrated to us, he said: Ibn ‘Uyaynah narrated to us, from al-Zuhri, from ‘Isa ibn Talhah, from ‘Abdullah ibn ‘Amr—if Allah wills—he said: A man came to the Prophet, may Allah bless him and grant him peace, and said: "I shaved before I slaughtered." He said: "Slaughter, and there is no harm." He said: "I slaughtered before I threw [the pebbles]." He said: "Throw, and there is no harm."
حدثنا أبو بكر قال حدثنا بن عيينة عن الزهري عن عيسى بن طلحة عن عبد الله بن عمرو إن شاء الله قال أتى النبي صلى الله عليه وسلم رجل فقال حلقت قبل أن اذبح قال فاذبح ولا حرج قال ذبحت قبل أن أرمي قال ارم ولا حرج
