That is why I say that if you protect your tongue then it will be easy 
to protect your other body parts (from committing sins). Hazrat Wala 
(Muhi-us-Sunnah Shah Abrar-ul-Haq Haqqi (RA)) used to do the following. 
If during the talk he picked up speed or his volume increased the he 
would immediately become completely silent. Or he would change the 
topic. Or he would leave.  Since that was the routine of my Shaikh I too
 follow the same. Once a person sought permission to visit Hazrat Wala 
(RA). Hazrat Wala (RA) wrote back that you can come but you do not have 
the permission to speak. He was permitted to listen only. When he came 
then he did not speak for some time but later started saying things. 
Hazrat Wala (RA) called him and reminded him of the condition. Since he 
had broken the agreement he was asked to leave. Similarly he person gave
 a gift to Hazrat Shah Wasiullah Sahab (RA). After some time he started 
offering his opinion about the things. Hazrat (RA) was puzzled. Then 
this person was called into seclusion. Hazrat (RA) had not used the gift
 given by that person. Hazrat (RA) said this is the thing that has 
inspired you to start commenting - now you have to take it back.
