Tongue and speaking ability is a blessing of Allah SWT for mankind and it differentiates human beings from the animals. Allah swt discusses this blessing in his book holy Quran in the following way:

Have We not made for him a pair of eyes? And a tongue and a pair of lips? (Al-Balad 90:8-9)

This tongue should always be used for good purpose with good intentions.A person is accountable before Allah swt for the blessing He has bestowed upon him.

Allah swt says:

Then, on that Day, you shall be asked about the blessings(you were given in this world)! (At-Takathur 102:8)

Some of the good deeds which can be done with the tongue are :

1 preaching /inviting to right path
2 Intercession
3 Consoling/kind words
4 words of wisdom

Positive saying is a very beneficial deed .A person who uses his tongue in a positive way gets reward from Allah swt for his good deed.

There are many verses of Quran highlighting importance of good sayings:

Some of the verses highlighting importance of preaching are as follows:
And who is better in speech than he who [says: "My Lord is Allâh (believes in His Oneness)," and then stands straight (acts upon His Order), and] invites (men) to Allâh's (Islâmic Monotheism), and does righteous deeds, and says: "I am one of the Muslims." (Fussilat 41:33)

You [true believers in Islâmic Monotheism, and real followers of Prophet Muhammad SAW and his Sunnah (legal ways, etc.)] are the best of peoples ever raised up for mankind; you enjoin Al-Ma'rûf (i.e. Islâmic Monotheism and all that Islâm has ordained) and forbid Al-Munkar (polytheism, disbelief and all that Islâm has forbidden), and you believe in Allâh. And had the people of the Scripture (Jews and Christians) believed, it would have been better for them; among them are some who have faith, but most of them are Al-Fâsiqûn (disobedient to Allâh - and rebellious against Allâh's Command). (Aali Imran 3:110)

Let there arise out of you a group of people inviting to all that is good (Islâm), enjoining Al-Ma'rûf (i.e. Islâmic Monotheism and all that Islâm orders one to do) and forbidding Al-Munkar (polytheism and disbelief and all that Islâm has forbidden). And it is they who are the successful. (Aali Imran 3:104)

Another verse highlighting importance of intercession is as follows:

Whosoever intercedes for a good cause will have the reward thereof, and whosoever intercedes for an evil cause will have a share in its burden. And Allâh is Ever All-Able to do (and also an All-Witness to) everything. (An-Nisa 4:85)

Similarly another verse highlighting importance of kind words is as follows:

Kind words and forgiving of faults are better than Sadaqah (charity) followed by injury. And Allâh is Rich (Free of all wants) and He is Most-Forbearing. (Al-Baqarah 2:263)

Similarly there are some of the verses highlighting importance of wisdom:

Invite (mankind, O Muhammad SAW) to the Way of your Lord (i.e. Islâm) with wisdom (i.e. with the Divine Inspiration and the Qur'ân) and fair preaching, and argue with them in a way that is better. Truly, your Lord knows best who has gone astray from His Path, and He is the Best Aware of those who are guided. (An-Nahl 16:125)

He grants Hikmah to whom He pleases, and he, to whom Hikmah is granted, is indeed granted abundant good. But none remember (will receive admonition) except men of understanding. (Al-Baqarah 2:269)

And indeed We bestowed upon Luqmân Al¬Hikmah (wisdom and religious understanding, etc.) saying: "Give thanks to Allâh," and whoever gives thanks, he gives thanks for (the good of) his ownself. And whoever is unthankful, then verily, Allâh is All¬Rich (Free of all wants), Worthy of all praise. (Luqman 31:12)
