He went as far as pushing for a "fatwa" – a ruling on a point of Islamic law – to be issued to require mixed-class marriages.
Under his hypothetical fatwa, "the poor are required to look for the rich [for marriage] and the rich should look for the poor".
He also suggested a "premarital certification programme" which would mean couples planning to tie the knot who were not financially secure would have to get a "pre-employment card" from a government programme.
"The goal is that after marriage, the couples will form economically stable households," he said.
According to the World Bank - an international financial institution that provides loans and grants to the governments of poorer countries with the aim of reducing poverty - Indonesia is the world's fourth most populous nation, the 10th largest economy in terms of purchasing power parity, and a member of the G-20.
It describes the nation as "an emerging lower middle-income country" which has "made enormous gains in poverty reduction, cutting the poverty rate by more than half since 1999, to 9.4 per cent in 2019".
