Four is mentioned in the Quran in these verses:
[2:226] Those who intend to divorce their wives shall wait four months (cooling off); if they change their minds and reconcile, then God is Forgiver, Merciful.
[2:234] Those who die and leave wives, their widows shall wait four months and ten days (before they remarry). Once they fulfill their interim, you commit no error by letting them do whatever righteous matters they wish to do. God is fully Cognizant of everything you do.
[2:260] Abraham said, “My Lord, show me how You revive the dead.” He said, “Do you not believe?” He said, “Yes, but I wish to reassure my heart.” He said, “Take four birds, study their marks, place a piece of each bird on top of a hill, then call them to you. They will come to you in a hurry. You should know that God is Almighty, Most Wise.”
[4:3] If you deem it best for the orphans, you may marry their mothers – you may marry two, three, or four. If you fear lest you become unfair, then you shall be content with only one, or with what you already have. Additionally, you are thus more likely to avoid financial hardship.
[4:12] You get half of what your wives leave behind, if they had no children. If they had children, you get one-fourth of what they leave. All this, after fulfilling any will they had left, and after paying off all debts. They get one-fourth of what you leave behind, if you had no children. If you had children, they get one-eighth of what you bequeath. All this, after fulfilling any will you had left, and after paying off all debts. If the deceased man or woman was a loner, and leaves two siblings, male or female, each of them gets one-sixth of the inheritance. If there are more siblings, then they equally share one-third of the inheritance. All this, after fulfilling any will, and after paying off all debts, so that no one is hurt. This is a will decreed by God. God is Omniscient, Clement.
[4:15] Those who commit adultery among your women, you must have four witnesses against them, from among you. If they do bear witness, then you shall keep such women in their homes until they die, or until God creates an exit for them.
[9:2] Therefore, roam the earth freely for four months, and know that you cannot escape from God, and that God humiliates the disbelievers.
[9:36] The count of months, as far as God is concerned, is twelve. This has been God’s law, since the day He created the heavens and the earth. Four of them are sacred. This is the perfect religion; you shall not wrong your souls (by fighting) during the Sacred Months. However, you may declare all-out war against the idol worshipers (even during the Sacred Months), when they declare all-out war against you, and know that God is on the side of the righteous.
[18:22] Some would say, “They were three; their dog being the fourth,” while others would say, “Five; the sixth being their dog,” as they guessed. Others said, “Seven,” and the eighth was their dog. Say, “My Lord is the best knower of their number.” Only a few knew the correct number. Therefore, do not argue with them; just go along with them. You need not consult anyone about this.
[24:4] Those who accuse married women of adultery, then fail to produce four witnesses, you shall whip them eighty lashes, and do not accept any testimony from them; they are wicked.
[24:5] If they repent afterwards and reform, then God is Forgiver, Merciful.
[24:6] As for those who accuse their own spouses, without any other witnesses, then the testimony may be accepted if he swears by God four times that he is telling the truth.
[24:7] The fifth oath shall be to incur God’s condemnation upon him, if he was lying.
[24:8] She shall be considered innocent if she swears by God four times that he is a liar.
[24:9] The fifth oath shall incur God’s wrath upon her if he was telling the truth.
[24:13] Only if they produced four witnesses (you may believe them). If they fail to produce the witnesses, then they are, according to God, liars.
[24:45] And God created every living creature from water. Some of them walk on their bellies, some walk on two legs, and some walk on four. God creates whatever He wills. God is Omnipotent.
[35:1] Praise be to God, Initiator of the heavens and the earth, and appointer of the angels to be messengers with wings – two, three, and four (wings). He increases the creation as He wills. God is Omnipotent.
[41:10] He placed on it stabilizers (mountains), made it productive, and He calculated its provisions in four days, to satisfy the needs of all its inhabitants.
[58:7] Do you not realize that God knows everything in the heavens and everything on earth? No three people can conspire secretly without Him being their fourth, nor five without Him being the sixth, nor less than that, nor more, without Him being there with them wherever they may be. Then, on the Day of Resurrection, He will inform them of everything they had done. God is fully aware of all things.
