I heard that if a Muslim person is killed by an intruder or dies by some accident or natural phenomena, he/she will go to Heaven directly. Is it true? Please tell me about it.
All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
It is proved in the sound Sunnah of the Prophet Muhammad that a person who is killed unjustly is considered a martyr, and so are those who are killed under building destruction or by fire.
Malik reported from the Hadeeth of Jabir Ibn 'Atik that the Prophet said: “There are seven categories of martyrs in addition to the one who is killed while fighting in the cause of Allah: (1) one who dies in plague is a martyr; (2) one who dies due to drowning is a martyr; (3) one who is killed of Dhat al-Janb disease (a disease that attacks ribs and causes inner ulcerations) is a martyr; (4) one who dies due to diseases of stomach is a martyr; (5) one who is killed by fire is a martyr; (6) one who is crushed under a wall is a martyr; and (7) a woman who dies while giving birth is a martyr.” [Abu Dawood and Ibn Majah]
An-Nawawi said while explaining Saheeh Muslim: “There is no difference of opinion that this Hadeeth reported by Malik is sound and authentic even though Al-Bukhari and Muslim did not report it.”
In another Hadeeth, the Prophet said: “One who is killed while defending himself; i.e., as a victim of injustice, is also a martyr.” [Ahmad and an-Nasaa-i]
Some Muslim scholars believe that one who is killed in a car accident is also a martyr since such a state is like being crushed under a wall, or like one who is killed in an accident and his car burst into flames.
However, there is no evidence that proves that the above-named categories of martyrs enter Paradise directly without being held for account. Such a state is in Allah's Hands. It will be enough to know that martyrs rank high in the sight of Allah Who promised to grant them Paradise.
Allah knows best.
