Question

                If a person dies by burning is he regarded as a martyr?.
Praise be to Allah.
      The one who dies by burning is a martyr, because of the 
      report narrated by Ahmad (23804), Abu Dawood (3111) and al-Nasaa’i (1846) 
      from Jaabir ibn ‘Ateek (may Allah be pleased with him), according to which 
      the Messenger of Allah (blessings and peace of Allah be upon him) said: 
      What do you regard as martyrdom?” They said: Being killed for the sake of 
      Allaah. The Messenger of Allaah (S) said: “Martyrdom is seven things 
      besides being killed for the sake of Allaah. The one who dies of the 
      plague is a martyr, the one who drowns is a martyr, the one who dies of 
      pleurisy is a martyr, the one who dies of a stomach disease is a martyr, 
      the one who is burned to death is a martyr, the one who dies beneath a 
      collapsed building is a martyr, and the woman who dies in pregnancy is a 
      martyr.”   

    Classed as saheeh by al-Albaani in Saheeh Abi Dawood. 

    It says in ‘Awn al-Ma‘bood Sharh Sunan Abi Dawood: 

    Al-Mat‘oon is the one who dies of the plague. The one who 
    drowns is a martyr if his journey was for a permissible purpose. The one who 
    dies of pleurisy – this refers to pain in a person’s side, which calmed down 
    and the pain ceased at the time of death; one of its signs is pain under the 
    ribs and difficulty in breathing, along with constant fever and coughing. It 
    is more common in women, according to al-Qaari. Al-mabtoon (the one who dies 
    of a stomach disease) refers to diarrhoea or dropsy or pain in the stomach. 
    The one who is burned to death refers to one who dies in a fire. The one who 
    dies beneath a collapsed building – this refers to falling walls and the 
    like. The woman who dies in pregnancy – al-Khattaabi said: what this means 
    is that she dies with a child in her womb. End quote. 

    And he said at the end: i.e., she dies with a child in her 
    womb. And it was said: this phrase [in Arabic] may refer to the woman who 
    dies a virgin. End quote. 

    Shaykh Ibn ‘Uthaymeen (may Allah have mercy on him) was 
    asked: If a man of the civil defence dies as a result of being burned with 
    fire when he was trying to put it out, is he regarded as a martyr? 

    He replied: Firstly, I say: everyone who dies by fire and is 
    a Muslim is one of the martyrs, because the Prophet (blessings and peace of 
    Allah be upon him) said: “the one who is burned to death is a martyr.” But 
    we cannot say that So and so is a martyr because he died by burning, because 
    we do not know. Rather we stay in general terms that everyone who dies by 
    burning is a martyr, and if he was a firefighter then he will attain a 
    greater reward, because the one who died seeking to put out a fire combined 
    two things: he was burned to death and he was protecting his brothers. So in 
    fact he has attained two rewards: the reward for protecting his Muslim 
    brothers and the reward of martyrdom for being burned to death. But you 
    should note that we do not testify for any particular individual, meaning 
    for example, that if a person is burned to death in front of us, we say “the 
    one who is burned to death is a martyr,” but we do not say “this man is a 
    martyr.” Al-Bukhaari (may Allah have mercy on him) referred to this issue in 
    his Saheeh and said: “Chapter: It cannot be said that So and so is a 
    martyr.” Then he quoted as evidence for that the words of the Prophet 
    (blessings and peace of Allah be upon him): “ … wounded for the sake of 
    Allah; Allah knows best who is wounded for His sake.” He said: Allah knows 
    best; therefore if Allah knows who is wounded for His sake, then we cannot 
    testify for anyone; rather we say in general terms that the one who is 
    killed for the sake of Allah is a martyr. Thus we differentiate between 
    speaking in general terms and speaking in specific terms.
