What is the ruling on one who dies from a stroke while traveling? Is he considered among the martyrs?

It has not been established that one who dies from a stroke or while traveling is a martyr. The hadith "The death of a stranger is martyrdom" is weak. However, another virtue has been reported for one who dies outside of their birthplace: that their place in Paradise will be measured from their birthplace to the end of their tracks. It was also said: their grave will be expanded for them and a door to Paradise will be opened for them.
