Waail bin Hajar reported,

I was sitting with the Messenger of Allah ﷺ when a man came with a rope around his neck. He said, "Messenger of Allah, this man and my brother were digging in a well together. He lifted the pickaxe and struck my brother on the head with it, killing him."The Prophet ﷺ said, "Pardon him."He refused and said, "Prophet of Allah, this man and my brother were digging in a well together. He lifted the pickaxe and struck my brother on the head with it, killing him."The Prophet said, "Pardon him."He refused. Then he stood up and said, "Messenger of Allah, this man and my brother were digging in a well together. He lifted the pickaxe and struck my brother on the head with it, killing him."The Prophet said, "Pardon him."He refused.The Prophet said, "Go, but if you kill him, you will be just like him."So he took him out, and when they had passed by, we called out to him, "Did you not hear what the Messenger of Allah ﷺ said?"He came back, and the Prophet said, "If you kill him, you will be just like him."He said, "Yes, I pardon him."Then he went out dragging his rope until he disappeared from our sight.

عن علقمة بن وائل عن أبيه قال

كنت قاعدا عند رسول الله ﷺ جاء رجل في عنقه نسعة فقال يا رسول الله إن هذا وأخي كانا في جب يحفرانها فرفع المنقار فضرب به رأس صاحبه فقتله فقال النبي ﷺ اعف عنه فأبى وقال يا نبي الله إن هذا وأخي كانا في جب يحفرانها فرفع المنقار فضرب به رأس صاحبه فقتله فقال اعف عنه فأبى ثم قام فقال يا رسول الله إن هذا وأخي كانا في جب يحفرانها فرفع المنقار أراه قال فضرب رأس صاحبه فقتله فقال اعف عنه فأبى قال اذهب إن قتلته كنت مثله فخرج به حتى جاوز فناديناه أما تسمع ما يقول رسول الله ﷺ فرجع فقال إن قتلته كنت مثله قال نعم أعف فخرج يجر نسعته حتى خفي علينا
