The Shaykh (Al-Mufid), may Allah
سبحانه وتعالى support him, then said: "Whoever washes his face and arms once during ablution (Wuduʾ) has fulfilled the obligation. If he washes these parts twice, he attains a reward, performs a meritorious act, and perfects his ablution." This is supported by Allah’s
سبحانه وتعالى statement: "When you stand up for prayer, wash your faces and your hands." (Surat al-Maʾidah,
5:6). Thus, whoever washes his face and arms once has complied with what the apparent meaning of the verse requires. Any additional washing requires specific evidence, and there is no evidence here to suggest that washing more than once is obligatory. This is further supported by the following evidence.
