Show mercy and forgive those who repent for their wrongdoings

This hadith speaks about justice, mercy, and forgiveness in Islam. It is narrated that a man killed another during the time of Prophet Muhammad (ﷺ). The killer was referred to the Prophet who handed him over to the victim's next of kin. However, when asked why he committed such an act, he said that it was unintentional. In response, Prophet Muhammad (ﷺ) warned them against killing him if he was telling the truth as it would lead them to Hellfire. He then let him go with a rope tied around his neck which earned him the name Dhan-Nis'ah or "the one with rope". This hadith teaches us that justice should be served but at same time we should also show mercy and forgive those who repent for their wrongdoings.
