Selam what is the proper way of positioning feet during sitting/ kneeling aspect of prayer. I see some websites instruct to sit on the L foot and right foot is erect. I like to sit on top of my heel while my feet are next to one another keeling of course. It is easier position for me to maintain because sometimes I have pain if I hyperextend my foot. Is my prayer valid or do I have to follow what those websites instruct? thx
Alaikumassalam wa rahmatullah,
The way of sitting you described is how the Prophet 
is said to have sat when praying. However, there is no hadith where the Prophet commands people to sit in this way. It is a way of copying the Prophet’s way of sitting, and we do not know with absolute certainty if it is the only correct way of sitting. So while we can consider it the recommended way of sitting, if you have difficulty sitting in that position then you can sit in whatever way is easiest for you. We know that Ibn Umar 
did not sit in the recommended way because it caused him pain due to an injury he had suffered in the past.
