Ju'ayd bin Abdur-Rahman narrates: I was with Sayyiduna al-Sa'ib bin Yazid (may Allah be pleased with him) when Zubayr bin Suhayl bin Abdur-Rahman bin Awf came to him, and there was a mark of prostration on his face. When he saw him, he asked: Who is this? It was said: It is Zubayr. He said: He has spoiled his face. Listen, by Allah! This is not the mark which Allah has mentioned in the Qur'an. I have prostrated on my face for eighty years, and yet prostration has not left any mark between my eyes.
