Love and Duty
Mohammad Ghazni had a slave named Ayaz, whom he loved very much. The other courtiers did not like this behaviour of the King. Someone asked the King, "Why do you love Ayaz so much?" After some time the King asked every one of the courtiers to smash down a very costly tree of diamonds which he had brought from India, and which was hung from the ceiling of the courthall. But none of his courtiers touched it. Then the King called Ayaz and commanded him to break down the diamond tree. Ayaz obeyed the command immediately and smashed it to pieces. The King told the courtiers, "Only because of this I love Ayaz. He considered it his duty to obey my command, and never bothered about the profit or loss."
