The word(s) "kindness" appears 18 time(s) in 18 verse(s) in Quran in Mohsin Khan translation.

(1) Thus We have made you [true Muslims - real believers of Islamic Monotheism, true followers of Prophet Muhammad صلى الله عليه وسلم and his Sunnah (legal ways)], a just (and the best) nation, that you be witnesses over mankind and the Messenger (Muhammad صلى الله عليه وسلم) be a witness over you. And We made the Qiblah (prayer direction towards Jerusalem) which you used to face, only to test those who followed the Messenger (Muhammad صلى الله عليه وسلم) from those who would turn on their heels (i.e. disobey the Messenger). Indeed it was great (heavy) except for those whom Allah guided. And Allah would never make your faith (prayers) to be lost (i.e. your prayers offered towards Jerusalem). Truly, Allah is full of kindness, the Most Merciful towards mankind.

(2) And of mankind is he who would sell himself, seeking the Pleasure of Allah. And Allah is full of kindness to (His) slaves.

(3) The divorce is twice, after that, either you retain her on reasonable terms or release her with kindness. And it is not lawful for you (men) to take back (from your wives) any of your Mahr (bridal-money given by the husband to his wife at the time of marriage) which you have given them, except when both parties fear that they would be unable to keep the limits ordained by Allah (e.g. to deal with each other on a fair basis). Then if you fear that they would not be able to keep the limits ordained by Allah, then there is no sin on either of them if she gives back (the Mahr or a part of it) for her Al-Khul' (divorce) . These are the limits ordained by Allah, so do not transgress them. And whoever transgresses the limits ordained by Allah, then such are the Zalimun (wrong-doers).

(4) On the Day when every person will be confronted with all the good he has done, and all the evil he has done, he will wish that there were a great distance between him and his evil. And Allah warns you against Himself (His punishment) and Allah is full of kindness to (His) slaves.

(5) And give not unto the foolish your property which Allah has made a means of support for you, but feed and clothe them therewith, and speak to them words of kindness and justice.

(6) And when the relatives and the orphans and Al-Masakin (the poor) are present at the time of division, give them out of the property, and speak to them words of kindness and justice.

(7) Allah has forgiven the Prophet (صلى الله عليه وسلم), the Muhajirun (Muslim emigrants who left their homes and came to Al-Madinah) and the Ansar (Muslims of Al-Madinah) who followed him (Muhammad صلى الله عليه وسلم) in the time of distress (Tabuk expedition), after the hearts of a party of them had nearly deviated (from the Right Path), but He accepted their repentance. Certainly, He is unto them full of kindness, Most Merciful.

(8) And they carry your loads to a land that you could not reach except with great trouble to yourselves. Truly, your Lord is full of kindness, Most Merciful.

(9) Or that He may catch them with gradual wasting (of their wealth and health). Truly! Your Lord is indeed full of kindness, Most Merciful?

(10) Until, when he reached the setting place of the sun, he found it setting in a spring of black muddy (or hot) water. And he found near it a people. We (Allah) said (by inspiration): "O Dhul-Qarnain! Either you punish them, or treat them with kindness."
