The word(s) "steadfast" appears 3 time(s) in 3 verse(s) in Quran in Muhammad Habib Shakir translation.

(1) O you who believe! be patient and excel in patience and remain steadfast, and be careful of (your duty to) Allah, that you may be successful.

(2) These shall be granted their reward twice, because they are steadfast and they repel evil with good and spend out of what We have given them.

(3) To this then go on inviting, and go on steadfastly on the right way as you are commanded, and do not follow their low desires, and say: I believe in what Allah has revealed of the Book, and I am commanded to do justice between you: Allah is our Lord and your Lord; we shall have our deeds and you shall have your deeds; no plea need there be (now) between us and you: Allah will gather us together, and to Him is the return.
