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

(51) O mankind! Verily, there has come to you a convincing proof (Prophet Muhammad صلى الله عليه وسلم) from your Lord; and We sent down to you a manifest light (this Qur'an).

(52) And (remember) when Musa (Moses) said to his people: "O my people! Remember the Favour of Allah to you when He made Prophets among you, made you kings and gave you what He had not given to any other among the 'Alamin (mankind and jinn, in the past)."

(53) "If you do stretch your hand against me to kill me, I shall never stretch my hand against you to kill you : for I fear Allah, the Lord of the 'Alamin (mankind, jinn, and all that exists)."

(54) Because of that We ordained for the Children of Israel that if anyone killed a person not in retaliation of murder, or (and) to spread mischief in the land - it would be as if he killed all mankind, and if anyone saved a life, it would be as if he saved the life of all mankind. And indeed, there came to them Our Messengers with clear proofs, evidence, and signs, even then after that many of them continued to exceed the limits (e.g. by doing oppression unjustly and exceeding beyond the limits set by Allah by committing the major sins) in the land!

(55) O Messenger (Muhammad صلى الله عليه وسلم)! Proclaim (the Message) which has been sent down to you from your Lord. And if you do not, then you have not conveyed His Message. Allah will protect you from mankind. Verily, Allah guides not the people who disbelieve.

(56) Say (O Muhammad صلى الله عليه وسلم to mankind): "How do you worship besides Allah something which has no power either to harm or benefit you? But it is Allah Who is the All-Hearer, All-Knower."

(57) Allah has made the Ka'bah, the Sacred House, an asylum of security and benefits (e.g.Hajj and 'Umrah) for mankind, and also the Sacred Month and the animals of offerings and the garlanded (people or animals marked with the garlands on their necks made from the outer part of the stem of the Makkah trees for their security), that you may know that Allah has knowledge of all that is in the heavens and all that is in the earth, and that Allah is the All-Knower of each and everything.

(58) The duty of the Messenger [i.e. Our Messenger Muhammad صلى الله عليه وسلم whom We have sent to you, (O mankind)] is nothing but to convey (the Message). And Allah knows all that you reveal and all that you conceal.

(59) Allah said: "I am going to send it down unto you, but if any of you after that disbelieves, then I will punish him with a torment such as I have not inflicted on anyone among (all) the 'Alamin (mankind and jinn)."

(60) So the root of the people who did wrong was cut off. And all the praises and thanks are to Allah, the Lord of the 'Alamin (mankind, jinn, and all that exists).
