Q.There is an individual in America who says the kuffar who died in the September 11th accidents or occurrences those individuals, the kuffaar who died in those buildings they were shuhooda (martyrs) is this correct?
A.The shaykh (haafidhahullaah) said a person who dies upon kuffar cannot be a martyr. A disbeliever who dies by way of fire or drowning, or a building collapsing on him or if he is killed, if he dies upon kuffar but dies by one of these means his abode will be the hellfire. The kuffar that die upon disbelief they will not be considered shuhooda.
