Bukhari vol. IV. No. 546: When Abdullah bin Salam heard of the arrival of the Prophet at Medina, he came to him and said, “I am going to ask you about three things which nobody knows except a prophet:1. What is the first sign of the Hour (i.e., the end of the world)?2. What will be the first meal taken by the people of Paradise?3. Why does a child resemble its father and why does it resemble its maternal uncle?”

Allah’s Apostle said, “Gabriel just now told me of their answers.” Abdullah said, “He (i.e., Gabriel), from amongst all the angels, is the enemy of the Jews.”

Allah’s Apostle said, “The first sign of the Hour will be a fire that will bring together the people from the East to the West; the first meal of the people of Paradise will be an extra lobe of fish-liver. As for the resemblance of the child to its parents: if a man has sexual intercourse with his wife and gets his discharge first, the child will resemble the father, and if the woman gets her discharge first, the child will resemble her.”

阿卜杜拉本賽萊來到先知那裏，?：“我要問你…只有一個先知才知道的事：…孩子為甚麼會像父親？和他為甚麼會像他舅舅？”使者?：“先知加百列（吉卜利里）剛告訴我答案。他是猶太人的敵人。如果一個男人與他妻子性交，他首先排出，孩子會像父親；如果女人首先排出，孩子會像她。”（布哈里聖訓4：55：546）
