Cf. 11:65 . An outline of the story of the Thamud is given in {7:73-79}.
Meaning, you have only three days to live. See 11:65.
Salih their prophet gave them three days' clear warning for repentance (xi. 65). But they heeded him not. On the contrary they flouted him and continued in their evil courses.
See the story of the Thamud and their prophet Salih in vii. 73-79. Here the point is the suddenness of their punishment and its unexpected nature.
