Beware Of Speaking Too Much — It Increases Mistakes And Engenders Boredom:

Islam Teaches us that a Muslim Should Control his Tongue and not Speak unless he has Something Good to say.
Islam prohibits sinful speech that intends to cause harm to other human beings. It also prohibits excessive laughter or extreme humor. People in general do not think twice about what they are saying.
They Forget that every word they utter is being recorded and will have to be accounted for on the Last Day.
The Prophet (saw) said: “Do not speak much without mentioning Allah, for too much speech without mentioning Allah hardens the heart, and the hard-hearted are the furthest of all people from Allah Most High.” (Tirmidhi)
Abu Hurairah (r.a) reported: “I heard the Prophet (peace be upon him) saying, “A person utters a word thoughtlessly (i.e. without thinking about its being good or not) and, as a result of this, he will fall down into the fire of Hell deeper than the distance between the east and the west.” (Bukhari and Muslim)
The Explanation given for these Hadith is from Imam Nawawi who explains: “Every legally responsible person should refrain from saying anything except when there is a clear advantage to speaking. Whenever speaking and not speaking are of equal benefit, it is Sunnah to remain silent, for permissible speech easily leads to that which is unlawful or offensive, as actually happens much or even most of the time — and there is no substitute for safety.”
Al-Tirmidhi also narrated that the Prophet (saw) said to Mu’adh (may Allah be pleased with him), after teaching him some of the laws of Islam, “Shall I not tell you what is the foundation of all that?” I [Mu’adh] said: “Of course, O Prophet of Allah.” He took hold of his tongue and said, “Control this.” I said, “O Prophet of Allah, will we be held responsible for what we say with it?” He said, “May your mother be bereft of you, O Mu’adh! Will the people be thrown into Hell on their faces or on their noses for anything other than the harvest of their tongues?”
The Hadith enjoins refraining from indulging in specific things because this is something that is of no benefit to a person, and indeed it may cause him a great deal of harm in his spiritual and worldly affairs.
Allah Hates Excessive, Exaggerated Speaking:
Abdullah ibn Amr reported: The Messenger of Allah (saw) said, “Verily, Allah despises an extravagant speaker among men, who flaps his tongue about like the flapping of a cow.” (Sunan al-Tirmidhī 2853)
An Intelligent Person’s mind is before his tongue. He thinks and ponders before he speaks. It is a sign of stupidity to talk before thinking and pondering.
Whoever does not keep a check on his tongue will regret it. For those who do good is good (reward) and even more than that.

“ Whoever Believes in Allah (swt) and the last day, let him speak good or else keep silent…”
Al-Nawawi said:“If he wants to speak, then if what he wants to say is good and he is confident that he will be rewarded for it, whether it is obligatory or praiseworthy, then let him speak, but if it does not seem to him that it is good and he will be rewarded for it, then let him refrain from speaking, whether he thinks it is haram (impermissible) or makrooh (disliked) or permissible.
Based on this, it is recommended to refrain from saying permissible words and we are enjoined to avoid this, lest it lead us into something that is haram or makrooh, which is what happens in many cases or in most cases. Allah says (interpretation of the meaning): ‘Not a word does he (or she) utter but there is a watcher by him ready (to record it).’ [50:18]
Al-Imam al-Shafi’i understood the Hadith (narration) to mean that if a person wants to say something, he should think about it: if it seems to him that it will not do any harm, then he should speak, but if he thinks that it will do some harm or he thinks that this is most likely, then he should refrain from speaking.”
How To Speak Less In Islam?
First of all, think before you speak and say what pleases Allah(swt). In conversation consider what you have to add, and trust that it’s what you say—not how much you say—that defines your impact.
Silence Makes The Heart Stronger:
Believers that speak a lot can harbor all sorts of illnesses like Ego, Grudge, or Hate in their Hearts.
However, Silence allows Inner Reflection that only leads to a clean and calmer heart purified of any disease and that’s why it is included in the Benefits of silence in Islam.
One can easily see how vain and idle talk can become a means to not only waste your time but also means that you are much more likely to gossip and backbite other people.
Therefore, make a conscious effort to be mindful of your speech and speak when you really need to.
"My Lord, expand for me my chest (with assurance) ease for me my task and untie the knot from my tongue that they may understand my speech".
"O' Allah Fill My Heart And Mind With True Enlightenment, Discerning Intelligence, Quick Understanding, And Knowledge, Verily Thou art able to do All Things".(Ameen).
