The word(s) "matter" appears 75 time(s) in 74 verse(s) in Quran in Mohsin Khan translation.

(21) If you help him (Muhammad صلى الله عليه وسلم) not (it does not matter), for Allah did indeed help him when the disbelievers drove him out, the second of the two; when they (Muhammad صلى الله عليه وسلم and Abu Bakr رضي الله عنه) were in the cave, he (صلى الله عليه وسلم) said to his companion (Abu Bakr رضي الله عنه): "Be not sad (or afraid), surely Allah is with us." Then Allah sent down His Sakinah (calmness, tranquillity, peace) upon him, and strengthened him with forces (angels) which you saw not, and made the word of those who disbelieved the lowermost, while the Word of Allah that became the uppermost; and Allah is All-Mighty, All-Wise.

(22) Verily, they had plotted sedition before, and had upset matters for you, until the truth (victory) came and the Decree of Allah (His religion, Islam) became manifest though they hated it.

(23) And of them are some who accuse you (O Muhammad صلى الله عليه وسلم) in the matter of (the distribution of) the alms. If they are given part thereof, they are pleased, but if they are not given thereof, behold! They are enraged!

(24) Say: "Is there of your (Allah's so-called) partners one that guides to the truth?" Say: "It is Allah Who guides to the truth. Is then He Who guides to the truth more worthy to be followed, or he who finds not guidance (himself) unless he is guided? Then, what is the matter with you? How judge you?"

(25) And for every Ummah (a community or a nation) there is a Messenger; when their Messenger comes, the matter will be judged between them with justice, and they will not be wronged.

(26) And indeed We sent Messengers before you (O Muhammad صلى الله عليه و سلم) and made for them wives and offspring. And it was not for a Messenger to bring a sign except by Allah's Leave. (For) every matter there is a Decree (from Allah). [Tafsir Al-Tabari]

(27) And Shaitan (Satan) will say when the matter has been decided: "Verily, Allah promised you a promise of truth. And I too promised you, but I betrayed you. I had no authority over you except that I called you, and you responded to me. So blame me not, but blame yourselves. I cannot help you, nor can you help me. I deny your former act in associating me (Satan) as a partner with Allah (by obeying me in the life of the world). Verily, there is a painful torment for the Zalimun (polytheists and wrong-doers)."

(28) And to Allah belongs the Unseen of the heavens and the earth. And the matter of the Hour is not but as a twinkling of the eye, or even nearer. Truly! Allah is Able to do all things.

(29) And do not kill anyone whose killing Allah has forbidden, except for a just cause. And whoever is killed wrongfully (Mazluman intentionally with hostility and oppression and not by mistake), We have given his heir the authority [to demand Qisas, - Law of Equality in punishment - or to forgive, or to take Diyah (blood money)]. But let him not exceed limits in the matter of taking life (i.e he should not kill except the killer). Verily, he is helped (by the Islamic law).

(30) He said: "So (it will be), your Lord said: 'That is easy for Me (Allah): And (We wish) to appoint him as a sign to mankind and a mercy from Us (Allah), and it is a matter (already) decreed, (by Allah).' "
