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

(1) Mothers shall suckle their children for two whole years; (that is) for those who wish to complete the suckling. The duty of feeding and clothing nursing mothers in a seemly manner is upon the father of the child. No-one should be charged beyond his capacity. A mother should not be made to suffer because of her child, nor should he to whom the child is born (be made to suffer) because of his child. And on the (father's) heir is incumbent the like of that (which was incumbent on the father). If they desire to wean the child by mutual consent and (after) consultation, it is no sin for them; and if ye wish to give your children out to nurse, it is no sin for you, provide that ye pay what is due from you in kindness. Observe your duty to Allah, and know that Allah is Seer of what ye do.

(2) And all married women (are forbidden unto you) save those (captives) whom your right hands possess. It is a decree of Allah for you. Lawful unto you are all beyond those mentioned, so that ye seek them with your wealth in honest wedlock, not debauchery. And those of whom ye seek content (by marrying them), give unto them their portions as a duty. And there is no sin for you in what ye do by mutual agreement after the duty (hath been done). Lo! Allah is ever Knower, Wise.

(3) O ye who believe! Squander not your wealth among yourselves in vanity, except it be a trade by mutual consent, and kill not one another. Lo! Allah is ever Merciful unto you.

(4) And some of them draw near unto others, mutually questioning.

(5) And some of them draw near unto others, mutually questioning.

(6) The day when He shall gather you unto the Day of Assembling, that will be a day of mutual disillusion. And whoso believeth in Allah and doeth right, He will remit from him his evil deeds and will bring him unto Gardens underneath which rivers flow, therein to abide for ever. That is the supreme triumph.
