The word(s) "mission" appears 63 time(s) in 55 verse(s) in Quran in Muhammad Habib Shakir translation.

(31) Those whom the angels cause to die while they are unjust to themselves. Then would they offer submission: We used not to do any evil. Aye! surely Allah knows what you did.

(32) And on the day when We will raise up a witness out of every nation, then shall no permission be given to those who disbelieve, nor shall they be made to solicit favor.

(33) And they shall tender submission to Allah on that day; and what they used to forge shall depart from them.

(34) Permission (to fight) is given to those upon whom war is made because they are oppressed, and most surely Allah is well able to assist them;

(35) Do you not see that Allah has made subservient to you whatsoever is in the earth and the ships running in the sea by His command? And He withholds the heaven from falling on the earth except with His permission; most surely Allah is Compassionate, Merciful to men.

(36) O you who believe! Do not enter houses other than your own houses until you have asked permission and saluted their inmates; this is better for you, that you may be mindful.

(37) But if you do not find any one therein, then do not enter them until permission is given to you; and if it is said to you: Go back, then go back; this is purer for you; and Allah is Cognizant of what you do.

(38) O you who believe! let those whom your right hands possess and those of you who have not attained to puberty ask permission of you three times; before the morning prayer, and when you put off your clothes at midday in summer, and after the prayer of the nightfall; these are three times of privacy for you; neither is it a sin for you nor for them besides these, some of you must go round about (waiting) upon others; thus does Allah make clear to you the communications, and Allah is Knowing, Wise.

(39) And when the children among you have attained to puberty, let them seek permission as those before them sought permission; thus does Allah make clear to you His communications, and Allah is knowing, Wise.

(40) Only those are believers who believe in Allah and His Apostle, and when they are with him on a momentous affair they go not away until they have asked his permission; surely they who ask your permission are they who believe in Allah and His Apostle; so when they ask your permission for some affair of theirs, give permission to whom you please of them and ask forgiveness for them from Allah; surely Allah is Forgiving, Merciful.
