The word(s) "chief" appears 84 time(s) in 79 verse(s) in Quran in Muhammad Habib Shakir translation.

(21) And do not lie in wait in every path, threatening and turning away from Allah's way him who believes in Him and seeking to make it crooked; and remember when you were few then He multiplied you, and consider what was the end of the mischief-makers.

(22) The chiefs, those who were proud from among his people said: We will most certainly turn you out, O Shu'aib, and (also; those who believe with you, from our town, or you shall come back to our faith. He said: What! though we dislike (it)?

(23) And the chiefs of those who disbelieved from among his people said: If you follow Shu'aib, you shall then most surely be losers

(24) Then we raised after them Musa with Our communications to Firon and his chiefs, but they disbelieved in them; consider then what was the end of the mischief makers.

(25) The chiefs of Firon's people said: most surely this is an enchanter possessed of knowledge:

(26) And the chiefs of Firon's people said: Do you leave Musa and his people to make mischief in the land and to forsake you and your gods? He said: We will slay their sons and spare their women, and surely we are masters over them.

(27) And We appointed with Musa a time of thirty nights and completed them with ten (more), so the appointed time of his Lord was complete forty nights, and Musa said to his brother Haroun: Take my place among my people, and act well and do not follow the way of the mischief-makers.

(28) And (as for) those who disbelieve, some of them are the guardians of others; if you will not do it, there will be in the land persecution and great mischief.

(29) And of them is he who believes in it, and of them is he who does not believe in it, and your Lord best knows the mischief-makers.

(30) Then did We send up after them Musa and Haroun to Firon and his chiefs with Our signs, but they showed pride and they were a guilty people.
