A Shaafi has not made qadhaa of some of his Ramadhaan fasts which he had missed three years ago.

Answer

Shaafis who delay their qadha fasting have to pay a penalty (Fidyah) for each fast. The Fidyah is the Sadqah Fitr amount. For each fast, in addition to making qadha, the Fidyah should be paid. Delay in this context means that the qadha was not made by the time the next Ramadhaan arrived.
