Actually this story about Moses is relevant and interesting.
Moses in trying to help one side of the two fighting, committed manslaughter. He refused to help the same person the next day, a point that changed his life after repenting and asking forgiveness for his mistake as per these verses :
Once he entered the city unexpectedly, without being recognized by the people. He found two men fighting; one was (a Hebrew) from his people, and the other was (an Egyptian) from his enemies. The one from his people called on him for help against his enemy. Moses punched him, killing him. He-Moses after realising- said, "This is the work of the devil; he is a real enemy, and a profound misleader."
He also said, "My Lord, I have wronged my soul. Please forgive me," and He forgave him. He is the Forgiver, Most Merciful.
He said, "My Lord, in return for Your blessings upon me, I will never be a supporter of the guilty ones."
قالَ رَبِّ بِما أَنعَمتَ عَلَىَّ فَلَن أَكونَ ظَهيرًا لِلمُجرِمينَ
In the morning, he was in the city, afraid and watchful. The one who sought his help yesterday, asked for his help again. Moses said to him, "You are really a troublemaker."
فَأَصبَحَ فِى المَدينَةِ خائِفًا يَتَرَقَّبُ فَإِذَا الَّذِى استَنصَرَهُ بِالأَمسِ يَستَصرِخُهُ قالَ لَهُ موسىٰ إِنَّكَ لَغَوِىٌّ مُبينٌ
Before he even attempted to strike this other common enemy- As from the previous verse, it seems he had no intention of getting involved-, he* this other Egyptian) said, "O Moses, do you want to kill me, as you killed the other man yesterday? Obviously, you wish to be a tyrant on earth; you do not wish to be righteous.
A man came running from the other side of the city, saying, "O Moses, the people are plotting to kill you. You better leave immediately. I am giving you good advice."
He fled the city, afraid and watchful. He said, "My Lord, save me from the oppressive people."
Then He run away towards Midyan.
As he traveled towards Midyan, he said, "May my Lord guide me in the right path."
May the Lord guide us in the right path.
GOD bless you all.
