If a sick person prays sitting down but is able to stand and recites al-Fatihah while rising, is the recitation valid?

Question : If he is sitting and is able to stand, he stands during the prayer, based on the generality of the statement: "Fear Allah as much as you are able." If he recites al-Fatihah while standing, during his rising, is the recitation of al-Fatihah valid?

Answer : He says it is not valid, because when he is able to stand, the obligation is to recite al-Fatihah while standing. However, the correct view is that it is valid. This rising is a transition from a lower state to a higher state according to his ability. We cannot tell him, "If you are able to stand while sitting, remain silent until you are fully standing," because such a transition to standing would not be quick; it would be slow. During this interval, he might recite two or three verses of al-Fatihah. If we say it is not valid, it means we are saying he must repeat this rak'ah. The correct ruling is that if he recites during his rising after being able to stand, his recitation in this state of rising is valid. Yes.
