Importance and benefits of Silence: Consequences of speaking constantly and without thinking

 Al-Imām an-Nawawi, [may Allāh bestow mercy upon him], said:

“Whosoever wishes to speak a word or sentence should reflect upon the consequences before speaking; if the advantages of doing so become clear, he should speak; otherwise, he should refrain from speaking.”
