Is the reward for congregational prayer recorded for someone who prayed forgetfully without purification in the mosque, then repeated the prayer after remembering at home?

If you realize the virtue of congregational prayer by going to pray with the congregation, believing yourself to be pure, but then it becomes clear that you were not, then Al-Nasa'i narrated from Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace be upon him) said: "Whoever performs ablution well, then goes to the mosque intending to pray, and finds that the people have already prayed, Allah will record for him a reward similar to that of those who attended it, and that will not decrease anything from their rewards." Al-Albani authenticated it. The believer is rewarded for merely intending if a compelling excuse prevents him. And whoever experiences this should seek another congregation to pray with. If he does not find one, he should pray alone, and he will be rewarded.
