The word(s) "again" appears 324 time(s) in 293 verse(s) in Quran in Mohsin Khan translation.

(41) Verily, those who believe, then disbelieve, then believe (again), and (again) disbelieve, and go on increasing in disbelief; Allah will not forgive them, nor guide them on the (Right) Way.

(42) O you who believe! Take not for Auliya' (protectors or helpers or friends) disbelievers instead of believers. Do you wish to offer Allah a manifest proof against yourselves?

(43) And because of their (Jews) disbelief and uttering against Maryam (Mary السلام عليهما) a grave false charge (that she has committed illegal sexual intercourse);

(44) And there is none of the people of the Scripture (Jews and Christians) but must believe in him ['Îsa (Jesus), son of Maryam (Mary), as only a Messenger of Allah and a human being] before his ['Îsa (Jesus) عليه السلام) or a Jew's or a Christian's] death (at the time of the appearance of the angel of death). And on the Day of Resurrection, he ['Îsa (Jesus)] will be a witness against them.

(45) Messengers as bearers of good news as well as of warning in order that mankind should have no plea against Allah after the (coming of) Messengers. And Allah is Ever All-Powerful, All-Wise.

(46) O you who believe! Remember the Favour of Allah unto you when some people desired (made a plan) to stretch out their hands against you, but (Allah) held back their hands from you. So fear Allah. And in Allah let the believers put their trust.

(47) Surely, in disbelief are they who say that Allah is the Messiah, son of Maryam (Mary) . Say (O Muhammad صلى الله عليه وسلم): "Who then has the least power against Allah, if He were to destroy the Messiah, son of Maryam (Mary), his mother, and all those who are on the earth together?" And to Allah belongs the dominion of the heavens and the earth, and all that is between them. He creates what He wills. And Allah is Able to do all things.

(48) "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)."

(49) The recompense of those who wage war against Allah and His Messenger and do mischief in the land is only that they shall be killed or crucified or their hands and their feet be cut off from opposite sides, or be exiled from the land. That is their disgrace in this world, and a great torment is theirs in the Hereafter.

(50) Verily, those who disbelieve, if they had all that is in the earth, and as much again therewith to ransom themselves thereby from the torment on the Day of Resurrection, it would never be accepted of them, and theirs would be a painful torment.
