Hazrat Mufti Ebrahim Salejee (Daamat Barakaatuhu) mentioned:
Misuse of the tongue can be extremely dangerous and disastrous. We don’t realise what trauma and disaster it can cause. The Hadeeth says: “Promise me the protection of the tongue, I promise you Jannat.” It is an extremely important matter. Even if you are right you need to think how to speak correctly.
