The Malikis are of the opinion that it is wajib for a nursing woman, not for a pregnant one. The Hanbalis and the Shafi`is say: Fidyah is wajib upon a pregnant and a nursing woman only if they fear danger for the child; but if they fear harm for their own health as well as that of the child, they are bound to perform the qada' only without being required to give fidyah.
The fidyah for each day is one mudd, which amounts to feeding one needy person (miskin.).1 • The Imamis state: If a pregnant woman nearing childbirth or the child of a nursing mother may suffer harm, both of them ought to break their fast and it is not valid for them to continue fasting due to the impermissibility of harm. They concur that both are to perform the qada' as well as give fidyah, equalling one mudd, if the harm is feared for the child.
But if the harm is feared only for her own person, some among them observe: She is bound to perform qada' but not to give fidyah, others say: She is bound to perform qada' and give fidyah as well. Travel, provided the conditions necessary for salat al-qasr, as mentioned earlier, are fulfilled as per the opinion of each school.
This is despite the observation of the Hanafis that performing salat as qasr during journey is compulsory and not optional. • The Imamis say: If the conditions required for praying qasr are fulfilled for a traveler, his fast is not acceptable. Therefore, if he fasts, he will have to perform the qada' without being liable to kaffarah.
This is if he starts his journey before midday, but if he starts it at midday or later, he will keep his fast and in the event of his breaking it will be liable to the kaffarah of one who deliberately breaks his fast.
