`Umar saw a silken cloak over a man for sale and requested the Prophet (ﷺ) to buy it in order to wear it on Fridays and while meeting delegates. The Prophet (ﷺ) said, "This is worn by the one who will have no share in the Hereafter." Later on Allah's Messenger (ﷺ) got some silken cloaks similar to that one, and he sent one to `Umar. `Umar said to the Prophet (ﷺ) "How can I wear it, while you said about it what you said?" The Prophet (ﷺ) said, "I have not given it to you to wear, but to sell or to give to someone else." So, `Umar sent it to his brother at Mecca before he embraced Islam.
Sahih al-Bukhari Book 51, Hadith 51
← Previous Hadith We were one-hundred and thirty persons accompanying the Prophet (ﷺ) who asked us whether anyone of us had food. There was a man who had about a Sa of wheat which was mixed with water then. A very tall pagan came driving sheep. The Prophet (ﷺ) asked him, "Will you sell us (a sheep) or give it as a present?" He said, "I will sell you (a sheep)." The Prophet (ﷺ) bought a sheep and it was slaughtered. The Prophet ordered that its liver and other Abdominal organs be roasted. By Allah, the Prophet (ﷺ) gave every person of the one-hundred-and-thirty a piece of that; he gave all those of them who were present; and kept the shares of those who were absent. The Prophet (ﷺ) then put its meat in two huge basins and all of them ate to their fill, and even then more food was left in the two basins which were carried on the camel (or said something like it).

Sahih al-Bukhari Book 51, Hadith 50 Next Hadith → My mother came to me during the lifetime of Allah's Messenger (ﷺ) and she was a pagan. I said to Allah's Apostle (seeking his verdict), "My mother has come to me and she desires to receive a reward from me, shall I keep good relations with her?" The Prophet (ﷺ) said, "Yes, keep good relation with her. "
