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

(11) Those who said of their brethren whilst they (themselves) held back: Had they obeyed us, they would not have been killed. Say: Then avert death from yourselves if you speak the truth.

(12) And do not give away your property which Allah has made for you a (means of) support to the weak of understanding, and maintain them out of (the profits of) it, and clothe them and speak to them words of honest advice.

(13) And when there are present at the division the relatives and the orphans and the needy, give them (something) out of it and speak to them kind words.

(14) And let those fear who, should they leave behind them weakly offspring, would fear on their account, so let them be careful of (their duty to) Allah, and let them speak right words.

(15) These are they of whom Allah knows what is in their hearts; therefore turn aside from them and admonish them, and speak to them effectual words concerning themselves.

(16) And (We sent) apostles We have mentioned to you before and apostles we have not mentioned to you; and to Musa, Allah addressed His Word, speaking (to him):

(17) O followers of the Book! do not exceed the limits in your religion, and do not speak (lies) against Allah, but (speak) the truth; the Messiah, Isa son of Marium is only an apostle of Allah and His Word which He communicated to Marium and a spirit from Him; believe therefore in Allah and His apostles, and say not, Three. Desist, it is better for you; Allah is only one Allah; far be It from His glory that He should have a son, whatever is in the heavens and whatever is in the earth is His, and Allah is sufficient for a Protector.

(18) Why do not the learned men and the doctors of law prohibit them from their speaking of what is sinful and their eating of what is unlawfully acquired? Certainly evil is that which they work.

(19) And do not approach the property of the orphan except in the best manner until he attains his maturity, and give full measure and weight with justice-- We do not impose on any soul a duty except to the extent of its ability; and when you speak, then be just though it be (against) a relative, and fulfill Allah's covenant; this He has enjoined you with that you may be mindful;

(20) And Musa's people made of their ornaments a calf after him, a (mere) body, which gave a mooing sound. What! could they not see that it did not speak to them nor guide them in the way? They took it (for worship) and they were unjust.
