Surah Al-Maidah (5:6) contains the detailed commandment about ablution (Wuzu). The verse prescribes: washing the face, washing both hands up to elbows, wiping the head, and washing both feet to the ankles. It also mentions Tayammum (dry ablution with clean earth) when water is unavailable. This verse provides the fundamental method of purification required before Salah and Quranic recitation.
