News about honeymoon packaged emerged after a beneficiary Abu Bilal al-Homsi disclosed this to a journalist via skype recently.
Homsi met his wife for the first time in Raqqa after months of chatting online.
They married and embarked upon their honeymoon by eating grilled meats in Raqqa's restaurants, strolling along the Euphrates River and enjoying ice cream.
It was all made possible by the marriage bonus he received from ISIS: $1,500 for him and his wife to get started on a new home, a family - and a honeymoon.
"It has everything one would want for a wedding,' al-Homsi said of Raqqa - a riverside provincial capital that in the 18 months since ISIS took control has seen militants beheading opponents and stoning alleged adulteresses in public."
The 28-year-old al-Homsi got a particularly large bonus because his new wife is a doctor and speaks four languages.
The couple is now expecting a new baby and hoping for another cash injection, as the group can pay up to $400 as a bonus for each child.
