Hadith.3287 - And Al-Hasan bin Zayd narrated something similar from Imam Jafar ibn Muhammad Al-Sadiq , from his father, Imam Muhammad ibn Ali Al-Baqir , who said: "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 . Umar said to Imam Ali ibn Abi Talib : '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 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 replied: 'The loss of his testicles is no different than the loss of some other part of his body.'"
