Silsilat al-Ahadith al-Sahihah

Ibn Abi Namla narrates from his father, he says: I was sitting with the Prophet Muhammad (peace be upon him) when a Jew came to him and said: O Muhammad! Is the dead spoken to? The Prophet (peace be upon him) said: “Allah knows best.” The Jew said: I bear witness that the dead are spoken to. The Prophet (peace be upon him) said: “When the People of the Book relate something to you, neither confirm nor deny them, but rather say: We believe in Allah, His Books, and His Messengers. If what they say is true, you have not denied it, and if it is false, you have not confirmed it.”
