When my father proposed to my mother… He dedicated Surah Al-Imran, which he memorized of heart, as her “Mahr” (dowry)
And when my husband proposed to me, my father told him that he would have to memorize a Surah of the Quran as my Mahr.. The wedding will not go on unless i’ve received my mahr 
I was asked to pick one of the surahs… I chose Surah Al-Noor… For all the laws that Surah contained within it and for the fact that it seemed hard to memorize on my behalf.
And before our wedding day; aside of being busy preparing for our “Newly wedded Nest”… The Quran wouldn’t leave my husband’s hand an entire month as he was memorizing the Surah…
A few days before our wedding day, my husband came to recite to my father the Surah which he had completed.
My father told him every time you make a mistake, you would have to start from the beginning all over again :))
My husband began reciting Surah Al-Noor with his calm/gentle voice in such a “beautiful” scene which I will never forget. My mother and I would look at one another and would smile awaiting my husband to make a mistake so he would have to start all over again and by that increase my “Reward”…
But my husband - May Allah bless him - had memorized the Surah of heart and didn’t even forget one single verse of it.
Once he finished my father hugged him and said to him: “Today I shall marry my daughter to u for u have fulfilled her mahr.. And your pledge to me..”
He didn’t pay me a financial Mahr… And we didn’t buy gold worth tens of thousands…
He sufficed me with Allah’s words as an oath/contract between us…
And the Question is…. I wonder what Surah my daughter will choose as her Mahr in the future?
Subhan’Allah, such a wonderful example.
