Is Washing Feet Required In Wudu?
The concept of Wuzu was well known with Arabs and with advent of Islam, it was instituted by Prophet Muhammad (sws) as Sunnah and people were following that. But when Quran wanted to talk about relaxation of Tayammum in this regard, then keeping in line with its special diction and style of language, it mentioned the whole wuzu process before mentioning the relaxation of Tayammum. And when Quran mentioned it, then this supercedes everything else. Now, the directive of Wuzu is to be extracted from the words of Quran only.
