Ali ibn AbuTalib:
The Prophet (ﷺ) said: There are three (persons) whose actions are not recorded: a sleeper till he awakes, a boy till he reaches puberty, and a lunatic till he comes to reason.
Abu Dawud said: Ibn Juraij has transmitted it from Al-Qasim b. Yazid on the authority of 'Ali from the Prophet (ﷺ). This version adds: "and an old man who is feeble-minded."
