The ruling on thinking about breaking off an act of worship, such as prayer, or the like

Question:
May Allah reward you. This questioner says: If a person is performing wudu' or praying, and he thinks about breaking off this wudu' or this prayer, and then he completes it and finishes it, is the wudu' or the prayer valid, or is it broken off merely by the thought?

Answer:
If this is a matter of waswas (whispers), then he should not pay attention to it. But if this is a matter of reality, meaning that he intended to break off the prayer, then the prayer is broken off. The prayer is broken off because the intention is lost, and one of the conditions for the validity of the prayer is the presence of the intention and its continuation until the completion of the prayer. If the intention is broken off, the prayer becomes invalid. Likewise, regarding purity: if he intends to break it off while he is performing wudu', his wudu' is broken off, and it is better for him to start it over from the beginning. However, if he completes the wudu' and finishes it, and then intends to break it off, it is not broken off except by a state of ritual impurity (hadath). If he completes the wudu' and finishes it, then intends to break it off, and then abandons that intention, his purity remains. Wudu' is not invalidated except by a state of ritual impurity (hadath). Yes.
