Praise be to Allah,
[Muhammad] ibn Abu ‘Adiyy narrated to us from Humayd [at-Taweel] from Anas ibn Maalik who said,
Abdullah ibn Salaam came to Allah’s Messenger (PBUH) when he had just arrived in Madeenah and said, ‘Messenger of Allah, I am going to ask you about three things which no one knows except a prophet.’ He said, ‘Ask whatever you want.’ He said, ‘What is the first sign of the Hour? What is the first food that the people of Paradise will eat? And how is it that a child may resemble either his father or his mother?’ Allah’s Messenger said, ‘Jibreel has just informed me about these matters.’ ibn Salaam said, ‘Jibreel is the enemy of the Jews from amongst all the angels.’ Allah’s Messenger (PBUH) then said, ‘The first sign of the Hour is a fire that will emerge from the east and drive people to the west. The first food that the people of Paradise will eat will be the caudate lobe of fish liver. As for the child resembling one parent or another, if the man’s [sexual] discharge precedes the woman’s discharge, the child will resemble him, but if the woman’s discharge precedes the man’s, the child will resemble her.’ ibn Salaam said, ‘I bear witness that there is no god but Allah and that you are Allah’s Messenger.’ He further said, ‘Messenger of Allah, the Jews are liars, and if they find out about my conversion to Islam, they will tell you that I am a liar. Send for them and ask them, ‘What is the position of Ibn Salaam amongst you?’ So he sent for them and asked them, ‘What is the position of (Abdullaah ibn Salaam amongst you?’ They said, ‘He is the best amongst us and the son of the best amongst us. He is our scholar and the son of our scholar, and he is the most knowledgeable of all of us and the son of the most knowledgeable of us .’ He said, ‘Do you think that if he becomes Muslim you will follow suit?’ They said, ‘May Allah save him from that! [He will never become Muslim] .’ Then [(Abdullaah ibn Salaam] came out and said, ‘I bear witness that there is no god but Allah and that Muhammad is the Messenger of Allah.’ They said, ‘He is the worst of us and the son of the worst of us; he is the most ignorant among us and the son of the most ignorant among us. Ibn Salaam said This is what I was afraid of.”‘
