The word(s) "speak" appears 76 time(s) in 70 verse(s) in Quran in Muhammad Habib Shakir translation.

(51) Allah has not made for any man two hearts within him; nor has He made your wives whose backs you liken to the backs of your mothers as your mothers, nor has He made those whom you assert to be your sons your real sons; these are the words of your mouths; and Allah speaks the truth and He guides to the way.

(52) O wives of the Prophet! you are not like any other of the women; If you will be on your guard, then be not soft in (your) speech, lest he in whose heart is a disease yearn; and speak a good word.

(53) Surely (as for) those who speak evil things of Allah and His Apostle, Allah has cursed them in this world and the here after, and He has prepared for them a chastisement bringing disgrace.

(54) And those who speak evil things of the believing men and the believing women without their having earned (it), they are guilty indeed of a false accusation and a manifest sin.

(55) O you who believe! be careful of (your duty to) Allah and speak the right word,

(56) On that day We will set a seal upon their mouths, and their hands shall speak to Us, and their feet shall bear witness of what they earned.

(57) A speaker from among them shall say: Surely I had a comrade of mine,

(58) What is the matter with you that you do not speak?

(59) He said: The truth then is and the truth do I speak:

(60) And they shall say to their skins: Why have you borne witness against us? They shall say: Allah Who makes everything speak has made us speak, and He created you at first, and to Him you shall be brought back.
