Pointing one's feet to a person or to Qibla is disrespectful. However, I am a fat man with heavy limbs and cannot sit with folded legs for more than a few minutes.

I saw Maulana Desai's answer to a question on the subject which says that pointing one's feet to a person or to Qibla is disrespectful. Of course, it seems natural. However, I am a fat man with heavy limbs and cannot sit with folded legs for more than a few minutes. So very often when I have to sit in the mosque, I have to stretch my legs leaning against the wall (I have back problem too). Allah knows I have not an iota of disrespect in my heart when I do this, but it is simply not possible for me to keep my legs folded except for a very short span. Please advise. I am anxiously waiting for a reply. Jazakamullah Khair
