Talkativeness and uncalled for speaking are one of the ways by which the heart dies and good spiritual mood is taken away from us. The Holy Prophet (PBUPH & HP) says: " if you were not addicted to excessive speaking, whatever I can see from the heavens, you could see as well and whatever I can hear, you could hear too".
Muhajj al-Bieza: 2/125
