Reports on a drunken person: is he lashed when sober or while drunk?

Abu Marwan said that al-Najashi the poet was brought to Sayyiduna Ali (may Allah be pleased with him) in Ramadan, intoxicated. He left him until he had sobered up, then gave him eighty lashes. Then he ordered that he be imprisoned, and the next day he brought him out and gave him twenty lashes, and said: "Eighty lashes for the wine and twenty lashes for your audacity against Allah in Ramadan."

Abu Majid al-Hanafi said: I was sitting with Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) when a man from the Muslims brought his nephew and said to him: "O Abu Abd al-Rahman, this is my brother's son; I have found him drunk." Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) said: "Shake him well, jostle him and smell his breath." So he was shaken and jostled and his breath was smelled, and he was found to be drunk. He was sent to prison. When the next day came, I came, and he too was brought.

Mughirah said that Ibrahim said: "When a person is drunk, he is to be left until he recovers, then he is to be flogged."

Mughirah said that al-Sha'bi said: "When the imam is drunk he is to be flogged while he is not in his senses, because if he comes to his senses he will prevent it."
