The word(s) "mutually" appears 3 time(s) in 3 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) When ye divorce women, and they fulfil the term of their ('Iddat), do not prevent them from marrying their (former) husbands, if they mutually agree on equitable terms. This instruction is for all amongst you, who believe in Allah and the Last Day. That is (the course Making for) most virtue and purity amongst you and Allah knows, and ye know not.

(2) Also (prohibited are) women already married, except those whom your right hands possess: Thus hath Allah ordained (Prohibitions) against you: Except for these, all others are lawful, provided ye seek (them in marriage) with gifts from your property,- desiring chastity, not lust, seeing that ye derive benefit from them, give them their dowers (at least) as prescribed; but if, after a dower is prescribed, agree mutually (to vary it), there is no blame on you, and Allah is All-knowing, All-wise.

(3) "Lead to destruction those whom thou canst among them, with thy (seductive) voice; make assaults on them with thy cavalry and thy infantry; mutually share with them wealth and children; and make promises to them." But Satan promises them nothing but deceit.
