'Adi (RAA) narrated, 'I asked the Messenger of Allah (ﷺ) about hunting using a featherless arrow (al-Mi'rad) [1]. He replied, "If The game is killed with its sharp edge (the iron piece) eat it; but if it strikes with the middle part of the shart (i.e. it is not penetrated with the sharp part) and the game is killed (due to being hit with it), it is considered a Mauqudhah [2], so do not eat it."
