Miracle of splitting a boulder

One week before the battle of trenches, the Sahabah were tirelessly digging a long trench to protect Madinah Munawwarah from a large army of non-Muslims. Our beloved Nabi ﷺ was also digging and helping when some sahaba came and complained about a large boulder/rock which was in their way and could not be broken.

Our beloved Nabi ﷺ went to the place of this boulder and struck it three times. 

With each strike a bright light appeared. Upon the third strike, this large rock crumbled to pieces! This was incredible considering the Sahaba were strong and trained for battle and our beloved Nabi ﷺ was able to do what they could not. 

Extraordinary right?!
