The ruling on praying while unaware of impurity and moving during prayer

The questioner:
Your Excellency the Shaykh, he says: He prayed in a garment that had impurity on it, unaware, and did not remember until after the prayer. What is required of him in this case?

The Shaykh:
His prayer is valid, and he should wash the garment. Yes.

The questioner:
Does he not repeat the prayer? No. Yes, may Allah bless you. This one is also asking, Shaykh, he says: What is the ruling on continuous movement in prayer without an excuse?

The Shaykh:
It is not disliked to have much movement in prayer. He (peace and blessings be upon him) said: He should be occupied in his prayer and focus on his prayer, leaving the movements that are not of the nature of the prayer. Yes.

The presenter:
Yes, may Allah bless you.
