When `Abdur-Rahman bin `Auf came to Medina and the Prophet (ﷺ) 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 (ﷺ) saw him wearing clothes stained with yellow perfume. The Prophet (ﷺ) asked, "What is this, O `Abdur-Rahman?" He said, "O Allah's Messenger (ﷺ)! I have married an Ansar' woman." The Prophet (ﷺ) 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."
Sahih al-Bukhari Book 63, Hadith 162
← Previous Hadith In the year of Hajjat-ul-Wada` the Prophet (ﷺ) visited me when I fell ill and was about to die because of that illness. I said, "O Allah's Messenger (ﷺ)! I am very ill as you see, and I am a rich man and have no heir except my only daughter. Shall I give 2/3 of my property in charity?" He said, "No." I said, "Shall I then give one half of it in charity?" He said, "O Sa`d! Give 1/3 (in charity) and even 1/3 is too much. No doubt, it is better to leave your children rich than to leave them poor, reduced to begging from others. And Allah will reward you for whatever you spend with the intention of gaining Allah's Pleasure even if it were a mouthful of food you put into your wives mouth." I said, "O Allah's Apostle! Am I to be left behind (in Mecca) after my companions have gone?" He said, "If you should be left behind, you will be upgraded and elevated for every deed you will do with a desire to achieve Allah's Pleasure. I hope that you will live long so that some people will benefit by you while others will be harmed. O Allah! Please fulfill the migration of my companions and do not make them turn back on their heels. But (we feel sorry for) the unlucky Sa`d bin Khaulah." Allah's Messenger (ﷺ) lamented his death in Mecca.

Sahih al-Bukhari Book 63, Hadith 161 Next Hadith → When the news of the arrival of the Prophet (ﷺ) 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 (ﷺ) 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 (ﷺ) 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 Messenger of Allah." and added, "O Allah's Messenger (ﷺ)! 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 (ﷺ) 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 (ﷺ) said, "What would you think if `Abdullah bin Salam should embrace Islam?" They said, "May Allah protect him from that." The Prophet (ﷺ) 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 Messenger 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 Messenger (ﷺ).
