Hadith 8:299
Abu Bakr narrated to us, he said: Abd al-A’la narrated to us, from Hisham, from al-Hasan, and from Hisham ibn Hassan, from Hisham ibn Urwah, from his father, that they both used to see no harm in a person in the state of ihram treating a wound of his with ghee and oil.
حدثنا أبو بكر قال ثنا عبد الأعلى عن هشام عن الحسن وعن هشام بن حسان عن هشام بن عروة عن أبيه أنهما كانا لا يريان بأسا أن يداوي المحرم جرحا له بالسمن والزيت
