Zakat

Bukhari :: Book 3 :: Volume 47 :: Hadith 769Narrated Abu Humaid Al-Sa'idi:
The Prophet appointed a man from the tribe of Al-Azd, called Ibn 'Utbiyya for collecting the Zakat. When he returned he said, "This (i.e. the Zakat) is for you and this has been given to my as a present." The Prophet said, "Why hadn't he stayed in his father's or mother's house to see whether he would be given presents or not? By Him in Whose Hands my life is, whoever takes something from the resources of the Zakat (unlawfully) will be carrying it on his neck on the Day of Resurrection; if it be a camel, it will be grunting; if a cow, it will be mooing; and if a sheep, it will be bleating." The Prophet then raised his hands till we saw the whiteness of his armpits, and he said thrice, "O Allah! Haven't I conveyed Your Message (to them)?"

Bukhari :: Book 3 :: Volume 47 :: Hadith 770Narrated Jabir:
The Prophet said to me, "I will give you so much (the Prophet pointed thrice with his hands) when funds of Bahrain will come to me." But the Prophet died before the money reached him. (When it came) Abu Bakr ordered an announcer to announce that whoever had a money claim on the Prophet or was promised to be given something, should come to Abu Bakr. I went to Abu Bakr and told him that the Prophet had promised to give me so much. On that Abu Bakr gave me three handfuls (of money).

Bukhari :: Book 3 :: Volume 47 :: Hadith 771Narrated Al-Miswar bin Makhrama:
Allah's Apostle distributed some cloaks but did not give anything thereof to Makhrama. Makhrama said (to me), "O son! accompany me to Allah's Apostle." When I went with him, he said, "Call him to me." I called him (i.e. the Prophet ) for my father. He came out wearing one of those cloaks and said, "We kept this (cloak) for you, (Makhrama)." Makhrama looked at the cloak and said, "Makhrama is pleased," (or the Prophet said), "Is Makhrama pleased?"
