By Allah, I will not leave him for anyone!

Jarir ibn ‘Abdullah al-Bajali (may Allah have mercy on him) reported that in a battle there was a man with Abu Musa al-Ash’ari (may Allah be pleased with him) who was very brave and damaging against the enemies.

After the battle they collected the booty. Abu Musa (may Allah be pleased with him) granted the man only a portion of the booty he deserved and not all. The man refused to accept anything less than what he deserved. As a result, Abu Musa (may Allah be pleased with him) gave him ten lashes and shaved off his head.

The man collected his hair and went off to ‘Umar (may Allah be pleased with him) as he was sitting in his gathering. He struck ‘Umar's chest with his hair and said, ‘I swear by Allah! If it wasn't for the fire of Hell, I would have dealt with your deputy myself!' He then related to him what Abu Musa (may Allah be pleased with him) did to him.

‘Umar then wrote to Abu Musa (may Allah be pleased with them both) saying, 'To proceed; So-and-so has related to me such-and-such. If you did this to him in public, then I swear you must also sit in public view so the man could exact revenge. If you did this to him in private then you may sit privately.'

The man took the letter to Abu Musa. The people said, 'Forgive him.'
The man said, 'By Allah, I will not leave him for anyone!'

When Abu Musa sat down for him to exact revenge, the man looked up at the sky and said, 'O Allah, I have forgiven him.'

Moral

From this story we can see the sheer amount of justice which is given to people in Islam, that even one of the commanders of the ruler is not exempt from being punished if he has wronged someone.
