One-fifth of Booty to the Cause of Allah (Khumus)
Bukhari :: Book 4 :: Volume 53 :: Hadith 390
Narrated Jabir bin 'Abdullah:
Allah's Apostle once said to me, "If the revenue of Bahrain came, I would give you this much and this much." When Allah's Apostle had died, the revenue of Bahrain came, and Abu Bakr announced, " Let whoever was promised something by Allah's Apostle come to me." So, I went to Abu Bakr and said, "Allah's Apostle said to me, 'If the revenue of Bahrain came, I would give you this much and this. much." On that Abu Bakr said to me, "Scoop (money) with both your hands." I scooped money with both my hands and Abu Bakr asked me to count it. I counted it and it was five-hundred (gold pieces). The total amount he gave me was one thousand and five hundred (gold pieces.)
Narrated Anas: Money from Bahrain was brought to the Prophet . He said, "Spread it in the Mosque." It was the biggest amount that had ever been brought to Allah's Apostle . In the meantime Al-'Abbas came to him and said, "O Allah's Apostle! Give me, for I gave the ransom of myself and Aqil." The Prophet said (to him), "Take." He scooped money with both hands and poured it in his garment and tried to lift it, but he could not and appealed to the Prophet, "Will you order someone to help me in lifting it?" The Prophet said, "No." Then Al-'Abbas said, "Then will you yourself help me carry it?" The Prophet said, "No." Then Al 'Abbas threw away some of the money, but even then he was not able to lift it, and so he gain requested the Prophet "Will you order someone to help me carry it?" The Prophet said, "No." Then Al-'Abbas said, "Then will you yourself yelp me carry it?" The Prophet said, 'No." So, Al-'Abbas threw away some more money and lifted it on his shoulder and went away. The Prophet kept on looking at him with astonishment at his greediness till he went out of our sight. Allah's Apostle did not get up from there till not a single Dirham remained from that money.
