It is narrated from Wuhayb that Zayd bin Thabit (may Allah be pleased with him) was in charge of the treasury during the reign of Uthman (may Allah be pleased with him). Uthman (may Allah be pleased with him) came and saw Wuhayb helping them, and asked: Who is this? He said: My slave. Uthman (may Allah be pleased with him) said: I see that he helps them; allot two thousand for him. So Zayd (may Allah be pleased with him) allotted him one thousand, or two thousand.
