Mukhtasar Bukhari

Narrated from Sayyiduna Abu Huraira (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "A man was walking on a path when he saw a branch of thorns lying on the road, so he removed it. Allah Almighty rewarded him for this by forgiving him." Then the Prophet (peace and blessings of Allah be upon him) said: "There are five types of martyrs: the one who dies of plague, the one who dies of a stomach illness, the one who drowns, the one who is crushed to death, and the one who is martyred in the way of Allah." The rest of the hadith has already passed (see the Book: The Statement of Adhan... Chapter: Drawing lots regarding Adhan...).
