The narration in Muslim is: Abul-Qasim (i.e., the Messenger of Allah) (PBUH) said, "He who points at his (Muslim) brother with a weapon is cursed by the angels even if the other person should be his real brother."
Commentary: "Silah" is that weapon which is used in war for attack and defense, i.e., sword, gun, pistol, lance, etc. To point any such weapon towards a Muslim or Dhimmi, even to frighten him, is forbidden. It is very unfortunate that, contrary to the teachings of Islam, display and use of weapons are very common nowadays so much so that the fashion of air fire festivities is gaining increasing popularity in Muslim society. This fashion is totally against the teachings of Islam and its dangerous consequences are witnessed everyday. May Allah grant us guidance to follow the Right Path.
