Lifting one's foot during salaah
Q: I read somewhere that you cannot lift your foot in prayer and it invalidates the prayer. But when I stand up from the sitting or prostration posture, I need to adjust my feet so that I am again facing qibla directly (my body seems to be a bit lost of the previous position). I heard it invalidates prayer. Hence if I am very slightly not facing qibla, I would just not lift my feet to adjust it. What should I do?
