Saeed bin Al-Musayyib (may Allah have mercy on him) said regarding the statement of Allah Almighty «وَعَلَى الَّذِينَ يُطِيقُونَهُ فِدْيَةٌ طَعَامُ مِسْكِينٍ» : This refers to the elderly person who used to fast but now does not have the strength, and the pregnant woman for whom fasting is difficult. It is obligatory upon both of them to feed a poor person for each day until Ramadan is completed.
