Hadith 8:2643
Abu Bakr narrated to us, he said: Sufyan ibn ‘Uyaynah narrated to us, from ‘Amr, from Abu al-Sha’tha’, regarding the muhrim (pilgrim in the state of ihram): He may remove the ticks from his camel and smear it with tar.
حدثنا أبو بكر قال نا سفيان بن عيينة عن عمر عن أبي الشعثاء المحرم يقرد بعيره ويطليه بالقطران
