And Abdur Rahman bin Awf, may Allah be pleased with him, said: When we migrated to Madinah, the Prophet (peace and blessings of Allah be upon him) established brotherhood between me and Sa’d bin Rabi’ Al-Ansari, may Allah be pleased with him. Abu Juhaifah, may Allah be pleased with him (Wahb bin Abdullah), said: The Prophet (peace and blessings of Allah be upon him) established brotherhood between Salman Al-Farsi and Abu Darda.

Narrated Anas: When `Abdur-Rahman bin `Auf came to Medina and the Prophet established the bond of brotherhood between him and Sa`d bin Ar-Rabi-al-Ansari, Saud suggested that `Abdur-Rahman should accept half of his property and family. `Abdur Rahman said, "May Allah bless you in your family and property; guide me to the market." So `Abdur-Rahman (while doing business in the market) made some profit of some condensed dry yoghurt and butter. After a few days the Prophet saw him wearing clothes stained with yellow perfume. The Prophet asked, "What is this, O `Abdur-Rahman?" He said, "O Allah's Apostle! I have married an Ansar' woman." The Prophet asked, "What have you given her as Mahr?" He (i.e. `Abdur-Rahman) said, "A piece of gold, about the weight of a date stone." Then the Prophet said, Give a banquet, even though of a sheep."

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.

Narrated Abu Al-Minhal `AbdurRahman bin Mut`im: A partner of mine sold some Dirhams on credit in the market. I said, "Glorified be Allah! Is this legal?" He replied, "Glorified be Allah! By Allah, when I sold them in the market, nobody objected to it." Then I asked Al-Bara' bin `Azib (about it) he said, "We used to make such a transaction when the Prophet came to Medina. So he said, 'There is no harm in it if it is done from hand to hand, but it is not allowed on credit.' Go to Zaid bin Al- Arqam and ask him about it for he was the greatest trader of all of us." So I asked Zaid bin Al-Arqam., and he said the same (as Al-Bara) did."

In Surah Al-Baqarah, the word «هادوا» means "became Jews," and in Surah Al-A'raf, «هدنا» is in the meaning of «تبنا» ("we repented"). From this, the meaning of «هائد» is «تائب» , that is, "one who repents."

Narrated Abu Huraira: The Prophet said, "Had only ten Jews (amongst their chiefs) believe me, all the Jews would definitely have believed me."

Narrated Abu Musa: When the Prophet arrived at Medina, he noticed that some people among the Jews used to respect Ashura' (i.e. 10th of Muharram) and fast on it. The Prophet then said, "We have more right to observe fast on this day." and ordered that fasting should be observed on it.

Narrated Ibn `Abbas: When the Prophet arrived at Medina he found that the Jews observed fast on the day of 'Ashura'. They were asked the reason for the fast. They replied, "This is the day when Allah caused Moses and the children of Israel to have victory over Pharaoh, so we fast on this day as a sign of glorifying it." Allah's Apostle said, "We are closer to Moses than you." Then he ordered that fasting on this day should be observed.

Narrated `Abdullah bin `Abbas: The Prophet used to keep his hair falling loose while the pagans used to part their hair, and the People of the Scriptures used to keep their hair falling loose, and the Prophet liked to follow the People of the Scriptures in matters about which he had not been instructed differently, but later on the Prophet started parting his hair.
