Hazrat Mufti Ebrahim Salejee (Daamat Barakaatuhu) mentioned:
We all wish to secure our rewards that are earned through ‘ibaadat. Hence, Nabi (sallallahu ‘alaihi wasallam) in a lengthy hadeeth explained to the Sahaabah (radhiyallahu ‘anhum) that the manner in which one would secure and preserve his rewards will be through the protection of the tongue. The misuse of the tongue can be extremely disastrous. A fifty year long standing friendly relationship can be shattered just by uttering one sentence. A long-lasting marriage can be broken just by the utterance of the words of divorce. Controlling the tongue is a means of earning oneself immense rewards.
