Narrated Zainab bint Um Salama: Um Sulaim said, "O Allah's Apostle! Verily Allah is not shy of (telling you) the truth. Is it essential for a woman to take a bath after she had a wet dream (nocturnal sexual discharge)?" He said, "Yes, if she notices discharge. On that Um Salama laughed and said, "Does a woman get a (nocturnal sexual) discharge?" He said, "How then does (her) son resemble her (his mother)?"

Narrated Um Salama: Um-Sulaim came to Allah's Apostle and said, "Verily, Allah is not shy of (telling you) the truth. Is it necessary for a woman to take a bath after she has a wet dream (nocturnal sexual discharge?) The Prophet replied, "Yes, if she notices a discharge." Um Salama, then covered her face and asked, "O Allah's Apostle! Does a woman get a discharge?" He replied, "Yes, let your right hand be in dust (An Arabic expression you say to a person when you contradict his statement meaning "you will not achieve goodness"), and that is why the son resembles his mother."

Narrated Anas: 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: What is the first portent of the Hour? What will be the first meal taken by the people of Paradise? 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." On that `Abdullah bin Salam said, "I testify that you are the Apostle of Allah." `Abdullah bin Salam further said, "O Allah's Apostle! The Jews are liars, and if they should come to know about my conversion to Islam before you ask them (about me), they would tell a lie about me." The Jews came to Allah's Apostle and `Abdullah went inside the house. Allah's Apostle asked (the Jews), "What kind of man is `Abdullah bin Salam amongst you?" They replied, "He is the most learned person amongst us, and the best amongst us, and the son of the best amongst us." Allah's Apostle said, "What do you think if he embraces Islam (will you do as he does)?" The Jews said, "May Allah save him from it." Then `Abdullah bin Salam came out in front of them saying, "I testify that None has the right to be worshipped but Allah and that Muhammad is the Apostle of Allah." Thereupon they said, "He is the evilest among us, and the son of the evilest amongst us," and continued talking badly of him.

Narrated Anas: When the news of the arrival of the Prophet at Medina reached `Abdullah bin Salam, he went to him to ask him about certain things, He said, "I am going to ask you about three things which only a Prophet can answer: What is the first sign of The Hour? What is the first food which the people of Paradise will eat? Why does a child attract the similarity to his father or to his mother?" The Prophet replied, "Gabriel has just now informed me of that." Ibn Salam said, "He (i.e. Gabriel) is the enemy of the Jews amongst the angels. The Prophet said, "As for the first sign of The Hour, it will be a fire that will collect the people from the East to the West. As for the first meal which the people of Paradise will eat, it will be the caudate (extra) lobe of the fish-liver. As for the child, if the man's discharge proceeds the woman's discharge, the child attracts the similarity to the man, and if the woman's discharge proceeds the man's, then the child attracts the similarity to the woman." On this, `Abdullah bin Salam said, "I testify that None has the right to be worshipped except Allah, and that you are the Apostle of Allah." and added, "O Allah's Apostle! Jews invent such lies as make one astonished, so please ask them about me before they know about my conversion to I slam . " The Jews came, and the Prophet said, "What kind of man is `Abdullah bin Salam among you?" They replied, "The best of us and the son of the best of us and the most superior among us, and the son of the most superior among us. "The Prophet said, "What would you think if `Abdullah bin Salam should embrace Islam?" They said, "May Allah protect him from that." The Prophet repeated his question and they gave the same answer. Then `Abdullah came out to them and said, "I testify that None has the right to be worshipped except Allah and that Muhammad is the Apostle of Allah!" On this, the Jews said, "He is the most wicked among us and the son of the most wicked among us." So they degraded him. On this, he (i.e. `Abdullah bin Salam) said, "It is this that I was afraid of, O Allah's Apostle.
