What is the required sequence when a wounded person needs Wudu (minor ablution) and the wound affects the face?
Chapter on Tayammum
Al-Mughni
Book of Purification
Primary text
If the wounded person requires Wudu and the injury is on the face such that no part of it can be washed, Tayammum must precede the Wudu Tayammum. If the wound affects only part of the face, the person has the choice: either wash the sound parts of the face first and then perform Tayammum to complete the Wudu, or perform Tayammum first, then wash the sound parts and complete the Wudu.

The Qadi asserts that sequence (tartib) is obligatory. If the wound affects only part of the face, the individual may choose between washing the sound part first followed by Tayammum, or performing Tayammum first followed by washing the sound part and completing the Wudu.
