Who is exempt from Jizyah in the Shafi'i school of thought?

I came across this claim: > Our school (Shafi'i) insists upon the payment of the poll-tax by sickly persons, old men, even if decrepit, blind men, monks, workmen, and poor persons incapable of exercising a trade. As for people who seem to be insolvent at the end of the year, the sum of the poll tax remained as debt to their account until they should become solvent." Imam nawawi My question is what is the official Shafi school opinion on who is exempt from paying Jizyah.
