Musannaf Ibn Abi Shaybah 89 — Running water between the fingers

Shaybah bin Nissah said: I travelled with al-Qasim bin Muhammad as far as Makkah. During ablution he would put the fingers of his hands between his toes and pour water over them. I asked him the reason for this, and he said: I saw Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) do just this.
