The word(s) "mankind" appears 291 time(s) in 273 verse(s) in Quran in Mohsin Khan translation.

(151) And among mankind is he who worships Allah as it were, upon the edge (i.e. in doubt): if good befalls him, he is content therewith; but if a trial befalls him, he turns back on his face (i.e. reverts to disbelief after embracing Islam). He loses both this world and the Hereafter. That is the evident loss.

(152) See you not that whoever is in the heavens and whoever is on the earth, and the sun, and the moon, and the stars, and the mountains, and the trees, and Ad-Dawabb [moving (living) creatures, beasts], and many of mankind prostrate themselves to Allah. But there are many (men) on whom the punishment is justified. And whomsoever Allah disgraces, none can honour him. Verily, Allah does what He wills.

(153) And proclaim to mankind the Hajj (pilgrimage). They will come to you on foot and on every lean camel, they will come from every deep and distant (wide) mountain highway (to perform Hajj ).

(154) That (Manasik- prescribed duties of Hajj is the obligation that mankind owes to Allah), and whoever honours the sacred things of Allah, then that is better for him with his Lord. The cattle are lawful to you, except those (that will be) mentioned to you (as exceptions). So shun the abomination (worshipping) of idol, and shun lying speech (false statements) -

(155) Thus it is [what has been mentioned in the above said Verses (27, 28, 29, 30, 31) is an obligation that mankind owes to Allah] and whosoever honours the Symbols of Allah, then it is truly from the piety of the hearts.

(156) Say (O Muhammad صلى الله عليه وسلم): "O mankind! I am (sent) to you only as a plain warner."

(157) See you not that Allah has subjected to you (mankind) all that is on the earth, and the ships that sail through the sea by His Command? He withholds the heaven from falling on the earth except by His Leave. Verily, Allah is, for mankind, Full of Kindness, Most Merciful.

(158) O mankind! A similitude has been coined, so listen to it (carefully): Verily those on whom you call besides Allah, cannot create (even) a fly, even though they combine together for the purpose. And if the fly snatches away a thing from them, they will have no power to release it from the fly. So weak are (both) the seeker and the sought.

(159) And strive hard in Allah's Cause as you ought to strive (with sincerity and with all your efforts that His Name should be superior). He has chosen you (to convey His Message of Islamic Monotheism to mankind by inviting them to His religion of Islam), and has not laid upon you in religion any hardship: it is the religion of your father Ibrahim (Abraham) (Islamic Monotheism). It is He (Allah) Who has named you Muslims both before and in this (the Qur'an), that the Messenger (Muhammad صلى الله عليه وسلم) may be a witness over you and you be witnesses over mankind! So perform As-Salat (Iqamat-as-Salat), give Zakat and hold fast to Allah [i.e. have confidence in Allah, and depend upon Him in all your affairs]. He is your Maula (Patron, Lord), what an Excellent Maula (Patron, Lord) and what an Excellent Helper!

(160) Then We sent Our Messengers in succession. Every time there came to a nation their Messenger, they denied him; so We made them follow one another (to destruction), and We made them as Ahadith (the true stories for mankind to learn a lesson from them). So away with a people who believe not!
