The word(s) "trust" appears 85 time(s) in 73 verse(s) in Quran in Mohsin Khan translation.

(51) A 'Ifrit (strong one) from the jinn said: "I will bring it to you before you rise from your place (council). And verily, I am indeed strong, and trustworthy for such work."

(52) So put your trust in Allah; surely, you (O Muhammad صلى الله عليه وسلم) are on manifest truth.

(53) And said one of them (the two women): "O my father! Hire him! Verily, the best of men for you to hire is the strong, the trustworthy."

(54) Those who are patient, and put their trust (only) in their Lord (Allah).

(55) And whosoever submits his face (himself) to Allah, while he is a Muhsin (good-doer i.e. performs good deeds totally for Allah's sake without any show off or to gain praise or fame and does them in accordance with the Sunnah of Allah's Messenger Muhammad صلى الله عليه وسلم), then he has grasped the most trustworthy handhold [La ilaha illallah (none has the right to be worshipped but Allah)]. And to Allah return all matters for decision.

(56) And put your trust in Allah, and Sufficient is Allah as a Wakil (trustee, or Disposer of affairs).

(57) And obey not the disbelievers and the hypocrites, and harm them not (in revenge for their harming you till you are ordered). And put your trust in Allah, and Sufficient is Allah as a Wakil (trustee, or Disposer of affairs). [Tafsir Al-Qurtubi]

(58) Truly, We did offer Al-Amanah (the trust or moral responsibility or honesty and all the duties which Allah has ordained) to the heavens and the earth, and the mountains, but they declined to bear it and were afraid of it (i.e. afraid of Allah's Torment). But man bore it. Verily, he was unjust (to himself) and ignorant (of its results).

(59) 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. "

(60) Verily, We have sent down to you (O Muhammad صلى الله عليه وسلم) the Book (this Qur'an) for mankind in truth. So whosoever accepts the guidance, it is only for his ownself, and whosoever goes astray, he goes astray only for his (own) loss. And you (O Muhammad صلى الله عليه وسلم) are not a Wakil (trustee or disposer of affairs, or guardian) over them.
