It is reported about Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that he said: In Allah Almighty's words, "and your feet up to the ankles", the command goes back to the washing of the feet.
Al-Tabarani recorded it in al-Mu'jam al-Kabir; the narrator Qatadah did not hear from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him).
