If a sick person wants to delay making his intention to fast until before the time of Zawal (midday), but he forgets and the time of Zawal passes, can he make his intention to fast when he remembers? Will his fast be valid?
In the name of Allah, the Beneficent, the Merciful
If the person intended to fast but was not able to express his intention verbally by midday, even then his fast would be valid.
And Allah knows best.
كما في المرقاة:والنية بتشديد الياء وقد تخفف لغة:القصر،و شرعاً:توجه القلب نحو الفعل ابتغاء لوجه الله،والقصد بها تمييز العبادة عن العادة اھ( 1/41)والله أعلم .
