What is the validity of applying the term "martyrs of duty" to security personnel when they fight aggressors?

Question:
He says: Honorable Shaykh, may Allah grant you success. The media refers to the security personnel who were killed (may Allah have mercy on them) in some confrontations with some aggressors as "martyrs of duty." What is the validity of this designation in terms of the Shari'ah?

Answer:
They do not testify for anyone regarding Paradise or Hellfire, or regarding martyrdom, except with evidence. If the Messenger of Allah (peace and blessings be upon him) testified that someone is a martyr, then we testify that he is a martyr. If he testified that someone is in Paradise, we testify that he is in Paradise. If the Messenger (peace and blessings be upon him) testified that someone is in Hellfire, we testify that he is in Hellfire. As for those for whom no testimony of Paradise or Hellfire has been given, we do not testify, but rather we hope for the doers of good and fear for the doers of evil. We do not assert Paradise or Hellfire for anyone except with evidence, whether they are security personnel or others. However, we hope for them martyrdom and we hope for them good from Allah (Glorified and Exalted is He), but we do not assert it. Yes.
