Mutarrif bin Abdullah bin al-Shikhkhir (may Allah have mercy on him) narrates from his father that he said: I came to the Messenger of Allah (peace and blessings be upon him) while he (peace and blessings be upon him) was reciting "Competition in increase diverts you" [Surah al-Takathur] , and he (peace and blessings be upon him) was saying: "The son of Adam says: My wealth, my wealth! Yet what is yours of your wealth except what you ate and consumed, or wore and wore out, or gave in charity and sent ahead?" The chain of this hadith is sahih (authentic), but it is not on the condition of the two Shaykhs (Bukhari and Muslim), because Abdullah bin al-Shikhkhir has no narrator other than his son Mutarrif. However, when I looked into it, I found that Imam Muslim recorded it in abridged form from the hadith of Shu'bah, narrated from Qatadah.

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that he said: The Messenger of Allah (peace and blessings be upon him) said: "I do not fear poverty (want) for you; rather, I fear for you the craving for abundance (the plenty of wealth and boasting about it). And I do not fear for you (unintentional) error; rather, I fear for you deliberate sinning." This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs (Bukhari and Muslim) did not record it.
