This is a powerful story of how important your dua is and how Allah will send His angels to respond.
A companion (ra) was travelling alone carrying goods to sell when he was confronted by a thief. The thief declared that he would steal the companion’s merchandise and then kill him. The companion begged him to relent but he refused, so he asked if he could perform just 2 rakat of prayer before his life was taken.
The dua he made in sujood was the difference between life and death.
