Testimony of a wine drinker: is it accepted or not?

It is narrated from Kardus (may Allah have mercy on him) that a young man was given the prescribed punishment (hadd) for wine. He later gave testimony before Shurayh (may Allah have mercy on him), who asked me about him. I said: He is one of the best of our young men. So he accepted his testimony.

Sayyiduna Umar (may Allah be pleased with him) wrote to Sayyiduna Abu Musa al-Ash'ari (may Allah be pleased with him): If a drinker of wine repents, accept his testimony.

Al-Sha'bi (may Allah have mercy on him) accepted the testimony of a person who had been given the prescribed punishment (hadd) for wine.
