The word(s) "chief" appears 78 time(s) in 70 verse(s) in Quran in Mohsin Khan translation.

(61) And they will say: "Our Lord! Verily, we obeyed our chiefs and our great ones, and they misled us from the (Right) Way.

(62) O mankind! Verily, the Promise of Allah is true. So let not this present life deceive you, and let not the chief deceiver (Satan) deceive you about Allah.

(63) "I had no knowledge of the chiefs (angels) on high when they were disputing and discussing (about the creation of Adam).

(64) Fir'aun (Pharaoh) said: "Leave me to kill Musa (Moses), and let him call his Lord (to stop me from killing him)! I fear that he may change your religion, or that he may cause mischief to appear in the land!"

(65) And indeed We did send Musa (Moses) with Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) to Fir'aun (Pharaoh) and his chiefs (inviting them to Allah's religion of Islam) He said: "Verily, I am a Messenger of the Lord of the 'Alamin (mankind, jinn and all that exists)."

(66) Would you then, if you were given the authority, do mischief in the land, and sever your ties of kinship?

(67) (The hypocrites) will call the believers: "Were we not with you?" The believers will reply: "Yes! But you led yourselves into temptations, you looked forward for our destruction; you doubted (in Faith) and you were deceived by false desires, till the Command of Allah came to pass. And the chief deceiver (Satan) deceived you in respect of Allah."

(68) They (hyprocrites) say: "If we return to Al-Madinah, indeed the more honourable ('Abdullah bin Ubai bin Salul, the chief of hyprocrites at Al-Madinah) will expel therefrom the meaner (i.e. Allah's Messenger صلى الله عليه وسلم)." But honour, power and glory belong to Allah, and to His Messenger (Muhammad صلى الله عليه وسلم), and to the believers, but the hypocrites know not.

(69) Because there came to him the blind man (i.e. 'Abdullah bin Umm-Maktum, who came to the Prophet صلى الله عليه وسلم while he was preaching to one or some of the Quraish chiefs).

(70) And made therein much mischief.
