The Bad Consequences of the Tongue
Part 2

The Tongue Expresses what is in the Heart:

If a person is good, it reflects in their saying. Allah has made it very easy for the tongue to move, and it is not difficult to realize that a person’s tongue moves much more as if compared to the limbs. So if a person is not careful about what he says, even a single saying of his can invalidate his actions. It is for this reason that the whole body warns the tongue saying, “Fear Allah concerning us, for we are (dependant) upon you. If you are upright then we will be upright and if you are corrupt then we will be corrupt.” - Sunan at-Tirmidhi (1912), Mishkaat (4838) and Riyaadh as-Saleheen (2/1521)

And at the same time, the tongue is a great blessing from Allah. If we look at the animals, who are unable to speak, we realize the importance of this great tool of communication.

The gratitude that we should show for this great blessing should include, using it for the obedience to Allah, for reading the Qur'aan, for seeking Knowledge, to enjoin good and forbidding evil. The prohibitions of the tongue are that you do not lie, abuse, use foul language, backbite and slander.

Allah says in the begining of Soorah al-Mumineen, “Indeed successful are the Believers, those who in their prayer have Khushoo’ (fear of Allah) and those who refrain from vain talk.” [Soorah Mumineen : 1-3]

Here Allah mentions that refraining from vain talk is a sign of the successful believers. Allah also mentions refraining from vain talk after he mentions al-Khushoo’. This is because too much talk makes the heart hard. It is not possible to reach the level of Khushoo’ (fear of Allah) unless one refrains from vain talk. 
Imaam an-Nawawee - rahimahullah - mentions “Know it is incumbent upon all to guard their tongues from most speech, except a word that has some benefit in it....” - Kitaabul-Adhkaar

And for those who take heed there is a constant reminder in the verse, “Not a word is said except that there is a watcher by him ready to record it.” - [Soorah Qaf (50):18]

The Messenger of Allah, Muhammed - SallAllahu 'alaihi wa sallam - said, “Whoever believes in Allah and the Last Day should speak good or keep silent.” 
Imaam ash-Shafiee - rahimahullah - said. “If you wish to speak then it is upon you to think before you speak. If you think there is good in it then speak and if not then do not speak.”

The earlier mentioned Qur'aanic verses, Hadeeth (sayings) of our noble Prophet and advices by the scholars of Islaam are a guide for those searching for salvation against vain talk. So before we talk, should we not ask ourselves....

  1. Will this saying of mine please Allah?
  2. Will this saying of mine bring me closer to Allah?
  3. Does this saying earn with it obedience to Allah?

If yes, then speak, otherwise one should keep quiet.
