Concept:The ayah that mentions “ill or on a journey… and ye find no water” deals with purification when water is unavailable.
Explanation:Muslims normally purify with water for prayer through
wuduˉ or
al−ghusl.
When water is absent, or using it is harmful due to illness or travel, Allah permits a substitute using clean earth.
This act is called
at-tayammum.
It involves striking clean soil lightly and wiping the face and hands.
The quoted statement matches the meaning of Qur’ān 5:6, even though the question refers to Q.5:7.
Therefore, the missing action in the verse is not
wuduˉ, not
al−ghusl, and not
qasr (shortening prayer).
The correct completion is
at-tayammum.
Answer:C. at-tayammum
