Shaykh Dr Zaid Alsalami is an Iraqi born scholar, raised in Australia. He obtained a BA from Al-Mustafa University, Qom, and an MA from the Islamic College in London. He also obtained a PhD from ANU, Canberra. He has written and translated several Islamic texts and also prepared educational videos on Islamic rulings and practices.
In an Islamic marriage contract, it is necessary to stipulate a nuptial gift, or what we call sidāq or mahr, and it can be anything that has a value, like teaching to recite Quran, or a copy of a Quran, etc.
There are many benefits of having such a mahr and not demanding high mahr. There is a statement from the holy Prophet (s.a.w.) that says the best of the women of my ummah is she with the less mahr.
Mahr is not a sign of love, or a security bond, but only a gesture and token of truthfullness, and anything spiritual will of course carry many benefits in this dunya and in akhirah.
With prayers for your success.
