The word(s) "happened" appears 6 time(s) in 6 verse(s) in Quran in Muhammad Pickthal translation.

(1) And marry not those women whom your fathers married, except what hath already happened (of that nature) in the past. Lo! it was ever lewdness and abomination, and an evil way.

(2) Forbidden unto you are your mothers, and your daughters, and your sisters, and your father's sisters, and your mother's sisters, and your brother's daughters and your sister's daughters, and your foster-mothers, and your foster-sisters, and your mothers-in-law, and your step-daughters who are under your protection (born) of your women unto whom ye have gone in - but if ye have not gone in unto them, then it is no sin for you (to marry their daughters) - and the wives of your sons who (spring) from your own loins. And (it is forbidden unto you) that ye should have two sisters together, except what hath already happened (of that nature) in the past. Lo! Allah is ever Forgiving, Merciful.

(3) O ye who believe! Kill no wild game while ye are on the pilgrimage. Whoso of you killeth it of set purpose he shall pay its forfeit in the equivalent of that which he hath killed, of domestic animals, the judge to be two men among you known for justice, (the forfeit) to be brought as an offering to the Ka'bah; or, for expiation, he shall feed poor persons, or the equivalent thereof in fasting, that he may taste the evil consequences of his deed. Allah forgiveth whatever (of this kind) may have happened in the past, but whoso relapseth, Allah will take retribution from him. Allah is Mighty, Able to Requite (the wrong).

(4) When ye were on the near bank (of the valley) and they were on the yonder bank, and the caravan was below you (on the coast plain). And had ye trysted to meet one another ye surely would have failed to keep the tryst, but (it happened, as it did, without the forethought of either of you) that Allah might conclude a thing that must be done; that he who perished (on that day) might perish by a clear proof (of His Sovereignty) and he who survived might survive by a clear proof (of His Sovereignty). Lo! Allah in truth is Hearer, Knower.

(5) He (the king) (then sent for those women and) said: What happened when ye asked an evil act of Joseph? They answered: Allah Blameless! We know no evil of him. Said the wife of the ruler: Now the truth is out. I asked of him an evil act, and he is surely of the truthful.

(6) Thus relate We unto thee (Muhammad) some tidings of that which happened of old, and We have given thee from Our presence a reminder.
