Assalamalecum wa rehmatullahi wa barakhatahu.Bismillah Ar Rehman Ar Raheem.friends most of us including me earlier think that islam is only doing salaah, fasting, zakah and hajj but in our day to day life we are way away from things that Allah and prophet Muhammad S.A.W ( pbuh ) wanted.one of the most important thing is good use of tongue.i see muslims who have beard not skipping salaah but totally opposite when speaking foul words.Allah had taken care of minute details in Quran for our development of every aspect.Allah in ch 2 v 83 of Quran has commanded mankind to speak fairly n nicely to others and when I tried to implement this believe me lot of quarrels and cold war witj others have abolished.moreover whenever you abuse someone you yourself doesn't feel good.so friends this tongue a small organ can make our surroundings peaceful or at the same time an unbearable place to live in.may Allah show us the right path.Ameen.
