Sunan Ibn Majah, 1526

It was narrated from Jabir bin Samurah that a man from among the Companions of the Prophet (ﷺ) was wounded, and the wound caused him a great deal of pain. He went and took a spearhead, and slaughtered himself with it. The Prophet (ﷺ) did not offer the funeral prayer for him, and that was as an admonition for others

Rapporté par Jabir bin Samurah : Un homme parmi les Compagnons du Prophète (ﷺ) a été blessé et sa blessure lui causait beaucoup de douleur. Il est allé prendre une pointe de lance et s’est donné la mort avec. Le Prophète (ﷺ) n’a pas accompli la prière funéraire pour lui, afin que cela serve d’avertissement aux autres
