If their interests were common they helped one another but if they were divergent they worked separately. The responsibility for corruption and mischief devolves on the chiefs belonging to all the three categories although the chiefs belonging to the last two categories had a larger hand in it.
They did not wish to miss any opportunity of gaining wealth and money and did not care as to how many responsibilities rested in those days on the shoulders of the Muslims in connection with the promotion of Islam. Signs of love for wealth and profit had begun appearing from beginning of the period of the caliphate of Abu Bakr. An evidence of this is the incident of Khalid bin Walid and the harsh words exchanged in that connection by Abu Bakr and Umar.
The story in short is that Khalid killed Malik bin Nuwaira cruelly and unjustly to acquire booty, and outraged the modesty of his wife, who was very beautiful. When the news reached Abu Bakr he was asto- nished and also felt grieved and uttered this well-known sentence. “War booty has made the Arabs greedy and Khalid has disobeyed my orders”. When Khalid came to see Abu Bakr he had three arrows in his turban. When Umar saw him he said: “O enemy of God! All these acts of yours are hypocritical.
By God if I gain control over you I shall stone you to death”. He then pulled the arrows from Khalid's turban and broke them. Khalid could not pick up courage to say anything as he was under the impression that Umar was acting in accordance with the instructions of Abu Bakr. Later Khalid saw Abu Bakr and put up excuses before him. Abu Bakr believed him and accepted his excuses.
When Umar came to know about this he incited Abu Bakr against Khalid and suggested that Khalid must be punished for killing Malik. Abu Bakr said: “O Umar! You had better keep quiet. Khalid is not the first person who has committed a mistake in the matter of interpretation (of law)”. During the days of Umar the distinguished persons of Quraysh also coveted worldly gains and there are innumerable instances which go to prove this fact.
The best proofs of it are the verses which a poet composed and sent to Umar. In those verses it had been said that in some cities and provinces the distinguished persons and dignitaries misappropriated public property and took care that he (Umar) should not come to know about it. It was added that the people were very much distressed owing to this exploitation. The poet says: “When they determine we also determine.
