Once a person asked me how to get over the habit of talking uselessly. I told him that this was very easy. One should always bear in mind this verse of the Quran: ‘The two recording angels are recording, sitting on the right and the left: each word he utters shall be noted down by a vigilant guardian.’ (50:17-18) Whatever word that a person utters is instantly noted down by the recording angels. One has to be cautious every moment about what one says. This gives a person the principle of refraining from idle, negative and hypocritical speech.
