The word(s) "slave" appears 166 time(s) in 153 verse(s) in Quran in Mohsin Khan translation.

(71) And on the Day when He will gather them together and that which they worship besides Allah [idols, angels, pious men, saints] . He will say: "Was it you who misled these My slaves or did they (themselves) stray from the (Right) Path?"

(72) And put your trust (O Muhammad صلى الله عليه وسلم) in the Ever Living One Who dies not, and glorify His Praises, and Sufficient is He as the All-Knower of the sins of His slaves,

(73) And the (faithful) slaves of the Most Gracious (Allah) are those who walk on the earth in humility and sedateness, and when the foolish address them (with bad words) they reply back with mild words of gentleness.

(74) "And this is the past favour with which you reproach me: that you have enslaved the Children of Israel."

(75) And We revealed to Musa (Moses), saying: "Depart by night with My slaves, verily you will be pursued."

(76) And indeed We gave knowledge to Dawud (David) and Sulaiman (Solomon), and they both said: "All the praises and thanks be to Allah, Who has preferred us above many of His believing slaves!"

(77) So he [Sulaiman (Solomon)] smiled, amused at her speech and said: "My Lord! Grant me the power and ability that I may be grateful for Your Favours which You have bestowed on me and on my parents, and that I may do righteous good deeds that will please You, and admit me by Your Mercy among Your righteous slaves."

(78) Say (O Muhammad صلى الله عليه وسلم): "Praise and thanks be to Allah, and peace be on His slaves whom He has chosen (for His Message)! Is Allah better, or (all) that you ascribe as partners (to Him)?" (Of course, Allah is Better).

(79) And those who had desired (for a position like) his position the day before, began to say: "Know you not that it is Allah Who enlarges the provision or restricts it to whomsoever He pleases of His slaves. Had it not been that Allah was Gracious to us, He could have caused the earth to swallow us up (also)! Know you not that the disbelievers will never be successful.

(80) O My slaves who believe! Certainly, spacious is My earth. Therefore worship Me." (Alone) .
