Where does one place his hands if he prays while sitting?

Question:
Muhammad says: What is the recommended practice (sunnah) for the one who is praying while sitting, whether to place his hands on his knees or on his chest? Some hadiths have come that indicate the prescribed nature of placing them on the knees, so what is the guidance?

Answer:
It is all permissible. If he places them on his knees or on his thighs, or places them on his chest while standing, or in a state that corresponds to standing, there is no harm in that. He has the choice. Yes.
