The discourse of the Sharia is directed at names and circumstances, not at individuals, so the ruling on the obligation is only upon the one whose condition is acceptance of the obligation, whether command and prohibition in action or omission. So whoever is unable to do any of that is what God has assigned him to do, but rather what he is addressed with. Indeed, God is not He has burdened every soul beyond its capacity, otherwise He has not given it. God will bring ease after hardship.
