Prayer sound

Soudabeh:
Prayer finds sound. Many times people pray that the affair doesn't take place. 
The person who  backbites indeed,  he prays that he himself wouldn't be a good success.
A person who slanders indeed he prays to slander him.  A person who doesn't pray indeed he prays to leave the obedience of God. Someone who doesn't  care about anyone actually he prays that no one will think of him. 
The universe is full of  the sounds and  the angels hear the sounds.  Since the angels are agent,  so they don't know who is the one who prays only they hear the sounds and follow the sounds.
The angels can never intercede only they hear the sounds and cut off the sustenance.
