It is narrated from Hazrat Anas bin Malik (may Allah be pleased with him) that after the arrival of the Prophet (peace and blessings be upon him) in Madinah Munawwarah, Hazrat Abdullah bin Salam (may Allah be pleased with him) came to the court of the Messenger and said, "O Messenger of Allah (peace and blessings be upon him)! I will ask you three things which no one knows except a Prophet." The Prophet (peace and blessings be upon him) said, "Ask." He said, "What is the very first sign of the Day of Judgment? What will be the first food of the people of Paradise? And how does a child resemble its parents?" The Prophet (peace and blessings be upon him) said, "Just now, Jibreel Amin (peace be upon him) has informed me of their answers." Abdullah said, "He is the enemy of the Jews among the angels." The Prophet (peace and blessings be upon him) said, "The very first sign of the Day of Judgment will be a fire that will emerge from the East and gather all the people in the West. The first food of the people of Paradise will be the liver of fish. As for the resemblance of a child to its parents, if the man's 'fluid' prevails over the woman's fluid, the child is drawn towards him, and if the woman's fluid prevails over the man's, the child is drawn towards her."
