Hadith 8:132
Abu Bakr narrated to us, he said: Jarir narrated to us, from Mansur, from Ibrahim and Mujahid, they both said: "If a person in Ihram complains of his tooth, he may extract it, and if it breaks, he may extract it." Mansur said: "And there is nothing upon him [i.e., no penalty]."
حدثنا أبو بكر قال ثنا جرير عن منصور عن إبراهيم ومجاهد قالا إذا اشتكى المحرم ضرسه نزعه وإذا انكسر نزعه قال منصور ولا شيء عليه
