Question: Is the pregnant woman and the breastfeeding woman required to make-up the fast [of the days missed in Ramadhaan] if they did not fast out of fear for their [unborn and breastfeeding] child? It’s just that I heard from some of the brothers that they are not required to do so. That is because they are included in the statement of Allaah:
Response: They are both required to make-up the fast [for the days missed in Ramadhaan] as well as feed a poor and needy person for every day [of fasting they missed]. That is because they [both] did not fast because of the[ir unborn and breastfeeding] child. [As for] the traveller and the menstruating woman, then they are only required to make-up the fast [for the days missed in Ramadhaan] – without [the need to] feed a poor and needy person [for every day of fasting they missed].
