The effect of improper Wudu' on the validity of Salah

Q: What is the ruling on Salah (Prayer) performed with imperfect Wudu' (ablution) regarding some parts of the body which are obligatory to be washed, such as the face, feet, and arms?

A: All the required parts of the body must be washed properly when performing Wudu'. If a Muslim performs Wudu' leaving some parts not touched by water, they have to (Part No. 4; Page No. 72) make water reach them. However, if these parts become dry due to the lengthy interruption, Wudu' must be performed again. If Salah is offered without repeating Wudu', both Wudu' and Salah must be performed again.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
