The word(s) "chief" appears 48 time(s) in 46 verse(s) in Quran in Muhammad Pickthal translation.

(11) The chieftains of his people, who were scornful, said: Surely we will drive thee out, O Shu'eyb, and those who believe with thee, from our township, unless ye return to our religion. He said: Even though we hate it?

(12) But the chieftains of his people, who were disbelieving, said: If ye follow Shu'eyb, then truly ye shall be the losers.

(13) Then, after them, We sent Moses with our tokens unto Pharaoh and his chiefs, but they repelled them. Now, see the nature of the consequence for the corrupters!

(14) The chiefs of Pharaoh's people said: Lo! this is some knowing wizard,

(15) The chiefs of Pharaoh's people said: (O King), wilt thou suffer Moses and his people to make mischief in the land, and flout thee and thy gods? He said: We will slay their sons and spare their women, for lo! we are in power over them.

(16) And when We did appoint for Moses thirty nights (of solitude), and added to them ten, and he completed the whole time appointed by his Lord of forty nights; and Moses said unto his brother, Aaron: Take my place among the people. Do right, and follow not the way of mischief-makers.

(17) Then, after them, We sent Moses and Aaron unto Pharaoh and his chiefs with Our revelations, but they were arrogant and were a guilty folk.

(18) And when they had cast, Moses said: That which ye have brought is magic. Lo! Allah will make it vain. Lo! Allah upholdeth not the work of mischief-makers.

(19) But none trusted Moses, save some scions of his people, (and they were) in fear of Pharaoh and their chiefs, that he would persecute them. Lo! Pharaoh was verily a tyrant in the land, and lo! he verily was of the wanton.

(20) And Moses said: Our Lord! Lo! Thou hast given Pharaoh and his chiefs splendour and riches in the life of the world, Our Lord! that they may lead men astray from Thy way. Our Lord! Destroy their riches and harden their hearts so that they believe not till they see the painful doom.
