The word(s) "therefore" appears 275 time(s) in 271 verse(s) in Quran in Muhammad Habib Shakir translation.

(71) And remember when He made you successors after Ad and settled you in the land-- you make mansions on its plains and hew out houses in the mountains-- remember therefore Allah's benefits and do not act corruptly in the land, making mischief.

(72) And to Madyan (We sent) their brother Shu'aib. He said: O my people! serve Allah, you have no god other than Him; clear proof indeed has come to you from your Lord, therefore give full measure and weight and do not diminish to men their things, and do not make mischief in the land after its reform; this is better for you if you are believers:

(73) (I am) worthy of not saying anything about Allah except the truth: I have come to you indeed with clear proof from your Lord, therefore send with me the children of Israel

(74) therefore We sent upon them widespread death, and the locusts and the lice and the frog and the blood, clear signs; but they behaved haughtily and they were a guilty people.

(75) therefore We inflicted retribution on them and drowned them in the sea because they rejected Our signs and were heedless of them.

(76) He said: O Musa! surely I have chosen you above the people with My messages and with My words, therefore take hold of what I give to you and be of the grateful ones.

(77) And when Musa returned to his people, wrathful (and) in violent grief, he said: Evil is it that you have done after me; did you turn away from the bidding of your Lord? And he threw down the tablets and seized his brother by the head, dragging him towards him. He said: Son of my mother! surely the people reckoned me weak and had well-nigh slain me, therefore make not the enemies to rejoice over me and count me not among the unjust people.

(78) And Musa chose out of his people seventy men for Our appointment; so when the earthquake overtook them, he said: My Lord! if Thou hadst pleased, Thou hadst destroyed them before and myself (too); wilt Thou destroy us for what the fools among us have done? It is naught but Thy trial, Thou makest err with it whom Thou pleasest and guidest whom Thou pleasest: Thou art our Guardian, therefore forgive us and have mercy on us, and Thou art the best of the forgivers.

(79) Say: O people! surely I am the Apostle of Allah to you all, of Him Whose is the kingdom of the heavens and the earth there is no god but He; He brings to life and causes to die therefore believe in Allah and His apostle, the Ummi Prophet who believes in Allah and His words, and follow him so that you may walk in the right way.

(80) therefore when they revoltingly persisted in what they had been forbidden, We said to them: Be (as) apes, despised and hated.
