This questioner says: Why does the one who prayed while forgetting without ablution have to repeat the prayer, while the one who prayed while forgetting and there was impurity on his garment does not have to repeat it?

Answer:

There is no disagreement among the scholars; the scholars hold that it is not among the conditions for the validity of the prayer. Yes.
