Slow sand

Slow sand was a powerful magical sand from Zakhara that literally had the power to stop time.

Powers
When thrown, this sand could affect up to three man-sized creatures so long as they stood within 10 feet (3 m) of each other, freezing each of them for up to 5 minutes similar to a hold person spell. Affected individuals entered a special stasis where they were unaffected by anything transpiring around them. A second handful of slow sand tossed on an individual in stasis increased the duration for one hour. Any creature able to resist the sand was merely slowed down for one minute.
