[The ruling on a person in ʿumrah who covered his head due to harm from fans]

Answer: The person performing ʿumrah remains bound by the sanctity of iḥrām until he finishes his saʿy between al-Ṣafā and al-Marwah; this is the madhhab, as in the marginalia of Sharḥ al-Azhār. On that basis, a fidyah is due from him: either fasting three days, or charity—feeding six needy persons, each a half ṣāʿ—or slaughtering a sheep.
