The word(s) "tell" appears 71 time(s) in 70 verse(s) in Quran in Mohsin Khan translation.

(51) And verily, if you ask them: "Who created the heavens and the earth?" Surely they will say: "Allah (has created them)." Say: "tell me then, the things that you invoke besides Allah - if Allah intended some harm for me, could they remove His harm? Or if He (Allah) intended some mercy for me, could they withhold His Mercy?" Say: "Sufficient for me is Allah; in Him those who trust (i.e. believers) must put their trust. "

(52) Have they taken (others) as intercessors besides Allah? Say: "Even if they have power over nothing whatever and have no intelligence?"

(53) And a believing man of Fir'aun's (Pharaoh) family, who hid his faith said: "Would you kill a man because he says: My Lord is Allah, and he has come to you with clear signs (proofs) from your Lord? And if he is a liar, upon him will be (the sin of) his lie; but if he is telling the truth, then some of that (calamity) wherewith he threatens you will befall on you." Verily, Allah guides not one who is a Musrif (a polytheist, or a murderer who shed blood without a right, or those who commit great sins, oppressor, transgressor), a liar!

(54) "And you will remember what I am telling you, and my affair I leave it to Allah. Verily, Allah is the All-Seer of (His) slaves."

(55) Say: "tell me, if it (the Qur'an) is from Allah, and you disbelieve in it? Who is more astray than one who is in opposition far away (from Allah's Right Path and His obedience).

(56) Say: "tell me! If this (Qur'an) is from Allah and you deny it, and a witness from among the Children of Israel ('Abdullah bin Salam رضي الله عنه) testifies that [this Qur'an is from Allah (like the Taurat (Torah)], and he believed (embraced Islam) while you are too proud (to believe)." Verily, Allah guides not the people who are Zalimun (polytheists, disbelievers and wrong-doers).

(57) Do their minds command them this [i.e. to tell a lie against you (Muhammad صلى الله عليه وسلم)] or are they people transgressing all bounds?

(58) Then tell Me (about) the (human) semen that you emit.

(59) Then tell Me about the seed that you sow in the ground.

(60) Then tell Me about the water that you drink.
