Muhammad bin Ziyad (may Allah have mercy on him) says: I heard Sayyiduna Abu Hurayrah (may Allah be pleased with him); he was passing by us while people were performing ablution from a vessel, and he said: Perform ablution completely, for Abu al-Qasim (peace and blessings be upon him) said: "Woe to the heels from the Fire!"
