Does the wudu' of one who washes some of the limbs three times and others once or twice, while in a hurry, become invalid?

Question:
He asks: Does the wudu' of one who washes some of the limbs three times and others once or twice, while in a hurry, become invalid?

Answer:
No, it does not become invalid. The obligatory act is one wash, and the second is a virtue. The third is a recommended practice (sunnah), and anything beyond the third is a religious innovation (bid'ah). If one limits himself to one comprehensive wash of the limb, that is sufficient. The obligatory act is one, and what is added to it is a recommended practice (sunnah) up to three. It is not required that every limb be washed three times. If some limbs are washed three times, some twice, and some once, this is sufficient. Yes.
