Q: I am 50 years old. I have been making namaaz regularly in the musjid daily all my life and for the past year or so. I make namaaz at home and only jumah in the musjid. This is due to chronic pain in my feet, toes and legs and I can't bend my toes anymore hence I sit on a chair when I make namaaz. I only go for jumah and don't sit on a chair at jumah. I make the two rakaat fard of jumah normal though I go through great pain. As soon as the fard is over I leave the musjid instantly. My great worry is that recently I read that we can't sit and make namaaz. The article read beware of the chair and stay away from the chair as namaaz on a chair is not accepted. I am in deep worry and cry a lot daily. I am unable to go for treatment to a private doctor or hospital as I am a pauper. I cannot go to government hospitals as every person I know with feet problems like mines land up with operations in the government hospitals but either loose their legs or land up with their feet being worse. I don't drink nor smoke. I strictly eat halaal food and live a clean life but still have this problem. I want to know if all my namaaz I made sitting is baatil. Yesterday I put pads around my feet and legs and attempted namaaz standing but the pain extends to my back. I am not cripple nor old aged and have no sickness so old age is not an excuse. Kindly advise what to do as I am unable to go for treatment so this pain becomes worse hence I will be sitting and makng namaaz.

Q: If a person is holding a handkerchief in his hand and performing salaah due to his nose running, his postures in salaah will be slightly changed, e.g. in sajdah he will hold his hand sideways or upside down so the hanky doesn't touch the floor, and in qadah his hand will be slightly lifted off his thigh with the hanky in between. Is it permissible to do so? What other options are there?
