It was narrated from ‘Abdullah bin ‘Abdullah bin Jabir bin ‘Atik, from his father, that his grandfather fell sick and the Prophet (ﷺ) came to visit him. One of his family members said: “We hoped that when he died it would be as a martyr in the cause of Allah.” The Messenger of Allah (ﷺ) said: “In that case the martyrs of my nation would be few. Being killed in the cause of Allah is martyrdom; dying of the plague is martyrdom; when a pregnant woman dies in childbirth that is martyrdom; and dying of drowning, or burning, or of pleurisy, is martyrdom.”
