"Umar bin Al-Khattab was presented with Qudamah bin Maz'un, who had drunk alcohol. Two men testified against him-one of them was a eunuch, Amr Al-Tamimi, and the other was Al-Mu'alla bin Al-Jarood. One of them testified that he saw him drinking, and the other testified that he saw him vomiting alcohol. Umar then sent for a group of the companions of the Messenger of Allah (swt), peace be upon him and his family, among them Commander of the Faithful Imam Ali ibn Abi Talib (as). Umar said to Imam Ali ibn Abi Talib (as): 'What do you say, O Abu Al-Hasan? For you are the one about whom the Messenger of Allah (swt), peace be upon him and his family, said: "The most knowledgeable of this nation and the one who judges with truth."' Imam Ali ibn Abi Talib (as) said: 'They have not differed in their testimony, for he would not have vomited it unless he had drunk it.' Umar then asked: 'Is the testimony of a eunuch acceptable?' Imam Ali ibn Abi Talib (as) replied: 'The loss of his testicles is no different than the loss of some other part of his body.'"
