Is the prayer of a man whose leg a dog licked valid if he completes his prayer?

The saliva of a dog is impure according to the majority of scholars. Therefore, if a person is touched by its saliva, their prayer becomes invalid, and they must repeat it. If they complete the prayer intentionally despite knowing this, they must repeat it. However, if they complete it out of ignorance, some scholars, like Ibn Taymiyyah, consider it valid. Nevertheless, it is more cautious to repeat it to avoid scholarly disagreement. For those who consider dog saliva pure, their prayer is valid.
