Is someone who dies in a car accident after returning from Tarawih prayers and buying Suhoor considered a martyr, and what is the difference between a martyr of this world and a martyr of the hereafter, and what is the reward of a martyr?

There is no text stating that death in a traffic accident is martyrdom, but some scholars have equated those who die in accidents with those who die under a collapse, which is mentioned as martyrdom. As for the difference between a martyr of this world (shahid al-dunya) and a martyr of the Hereafter (shahid al-akhira): A martyr of this world is one who is killed in jihad out of ostentation or for a worldly purpose, and is treated as a martyr in this world (not washed or prayed over). A martyr of both this world and the Hereafter is one who is killed in jihad for the sake of Allah with sincerity. As for a martyr of the Hereafter only, he is given the reward of a martyr on the Day of Judgment, but he is washed and prayed over in this world.
