"Ibn Mirba Al-Ansari came to us while we were standing at our places" (Amr bin Sinar said:) a place that Amr (bin Abdullah) indicated was far - "and he said: 'I am a messenger whom the Messenger of Allah sent to you to say: 'Stay with your (Hajj) rites, for indeed you are following a legacy left by Ibrahim.'"
Jami` at-Tirmidhi Book 9, Hadith 76
