وَالْحَامِلُ وَالْمُرْضِعُ إِذَا خَافَتَا عَلَى وَلَدَيْهِمَا: أَفْطَرَتَا وَقَضَتَا، وَلَا فِدْيَةَ عَلَيْهِمَا.
Translation: If a pregnant woman and a nursing woman fear harm to their children, they may omit the fast and make it up later; no fidyah is due from them.
The phrase “ʿalā waladayhimā” explicitly identifies fear for their children. Where the stated concern warrants omitting fasting, the missed fasts are made up later and no additional fidyah is due under this Hanafi ruling.
This is postponement of performance, not replacement by a financial payment. Pregnancy or nursing in itself should not be treated as a universal authorization to miss every fast; the relevant harm must be credible.
