A tongue has no bones,but it can break a heart and also it can be a pillar of strength to a broken heart.
Use it carefully.
Fight your tongue for the tongue is quick to kill a man. The tongue is
the posting of the heart as it shows man his intellect - Abdullah ibn
al-Mubarak
“The Muslim is he
from whose tongue and hand the Muslims are safe, and the Emigrant is he
who abandons what God has prohibited.”
Narrated Abdullah bin Amr
(RAA), the Prophet (SAW) said, "A Muslim is the one who avoids harming
Muslims with his tongue and hands. A Muhajir is the one who gives up all
that Allah (SWT) has forbidden.
