Punishment of supporting the murder of a believer with a few words

2. My father رحمه الله said: it was narrated to me by Sa’d b. Abdillah from Ahmad b. Muhammad from Ahmad from al-Hussain b. Sa’eed from Muhammad b. Abi ’Umayr from Hamad b. Uthman from Abi Abdillah عليه السلام or from the one who mentioned it to him who said: Imam Ja’far Sadiq عليه السلام narrates that while accounting of deeds will be going on, a person will come forward and soak another person in blood. He will be asked the reason for doing so. He will reply, “On so and so day he had spoken a few words due to which I was murdered.”
