The word(s) "mahr" appears 23 time(s) in 14 verse(s) in Quran in Mohsin Khan translation.

(11) O Prophet (Muhammad صلى الله عليه وسلم)! Verily, We have made lawful to you your wives, to whom you have paid their mahr (bridal-money given by the husband to his wife at the time of marriage), and those (slaves) whom your right hand possesses - whom Allah has given to you, and the daughters of your 'Amm (paternal uncles) and the daughters of your 'Ammat (paternal aunts) and the daughters of your Khal (maternal uncles) and the daughters of your Khalat (maternal aunts) who migrated (from Makkah) with you, and a believing woman if she offers herself to the Prophet, and the Prophet wishes to marry her - a privilege for you only, not for the (rest of) the believers. Indeed We know what We have enjoined upon them about their wives and those (slaves) whom their right hands possess, in order that there should be no difficulty on you. And Allah is Ever Oft-Forgiving, Most Merciful.

(12) And in their properties there was the right of the Sa'il (the beggar who asks) and the mahrum (the poor who does not ask others) .

(13) O you who believe! When believing women come to you as emigrants, examine them; Allah knows best as to their Faith, then if you ascertain that they are true believers send them not back to the disbelievers. They are not lawful (wives) for the disbelievers nor are the disbelievers lawful (husbands) for them. But give them (the disbelievers) that (amount of money) which they have spent [as their mahr] to them. And there will be no sin on you to marry them if you have paid their mahr to them. Likewise hold not the disbelieving women as wives, and ask for (the return of) that which you have spent (as mahr ) and let them (the disbelievers) ask back for that which they have spent. That is the Judgement of Allah, He judges between you. And Allah is All-Knowing, All-Wise.

(14) And if any of your wives have gone from you to the disbelievers, (as apostates and you asked them to return back your mahr but they refused) - then you went out for a Ghazwah (military expedition) (against them and) gained booty; then pay from that booty to those whose wives have gone, the equivalent of what they had spent (on their mahr ). And fear Allah in Whom you believe.
