Eating or lifting one's feet of the ground in Salaah
Q: To pray Salaah without making intention, to eat during Salah, to lift your feet during Salah, to lift your hands and to make an expression which makes a person looking think that you are not in Salah all make your Salah invalid. If I have done any of these actions whilst not knowing that these break Salah, do I have to do Qadha for them?
