Purifying wealth by hosting guests, feeding the poor and the like

Sayyiduna Ibrahim bin Abd al-Rahman bin Awf narrates from his father that the Messenger of Allah (peace and blessings be upon him) said to him: "O Ibn Awf! You are among the wealthy, and you will enter Paradise crawling. So lend to Allah (spend in His path), and He will free your feet." Ibn Awf said: O Messenger of Allah! What shall I lend to Allah? He (peace and blessings be upon him) said: "Give up what you have." He asked: All of it? He said: "Yes." Ibn Awf had just gone out with that intention when the Messenger of Allah (peace and blessings be upon him) sent for him and said: "Jibril came to me and said: Instruct Ibn Awf to host guests, feed the needy, give to the one who asks, and begin (his spending) with his own dependants, for when he does that, it will be a means of purifying the rest of his wealth."
This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "The best of you after me is the one who is best to my family." Quraysh said: Muhammad bin Amr told me, from Abu Salamah, that his father (Abd al-Rahman bin Awf) had bequeathed to the Mothers of the Believers a garden which, after him, was sold for forty thousand dinars.
This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs did not record it, and it has an authentic supporting narration (shahid) on the condition of the two Shaykhs (Bukhari and Muslim).

Abu Salamah bin Abd al-Rahman narrates: I went to Sayyidah Aishah (may Allah be pleased with her), and she said to me that the Messenger of Allah (peace and blessings be upon him) used to say to her: "Your affair is among the things that concern me after me, and none will remain steadfast (in treating) you (well) except those who are patient." Then Sayyidah Aishah (may Allah be pleased with her) would say: May Allah give your father to drink from Salsabil in Paradise, for Abd al-Rahman bin Awf had sent them (the Mothers of the Believers) wealth which was sold for forty thousand.
