Is the method of washing the feet in Wudu, with rubbing and passing the index finger between the toes, sufficient without counting the washes?

Performing Wudu (ablution) by washing the limbs once is sufficient. Scholars have unanimously agreed that washing the limbs once is obligatory, and repeating the wash two or three times is a Sunnah (definition). This is supported by the Hadith (definition) narrated by Ibn Abbas (may Allah be pleased with them both) that the Prophet (peace be upon him) "performed Wudu, washing each part once." The variation in the narrations concerning the number of washes indicates that all are permissible, but washing three times is the most complete, while washing once is sufficient. However, one should not always wash only once and thus deprive oneself of additional reward.
