Zaid bin Khalid al-Juhani reported the Messenger of Allah ﷺ as saying: "Shall I not tell you of the best witnesses ? He is the one who produces his deposition or gives his evidence (the narrator is doubtful) before he is asked for it. " Abdullah bin Abi Bakr dobted which of them he said. Abu Dawud said: Malis said: This refers to a man gives his evidence, but he does not know for whom it is meant. Al-Hamdani said: "He should inform the authorities. Ibn al-Sarh said: "He should give it to the ruler. The work ikhbar (inform) occurs in the version of al-Hamdani. " Ibn al-Sarh said: "Ibn Abi Amrah and not Abdur-Rahman. "
