The Hadith is replete with absurd stories. One such story is as follows:
Anas reports that when 'Abdullah bin Salam heard 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 portent of the Hour? 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 has 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 portent 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 Extra-lobe (caudate 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 discharge first, the child will resemble the father, and if the woman gets discharge first, the child will resemble her." ~ Sahih Bukhari, Vol. 4, Book 55, #546.
