What is the ruling on using the right hand for istinja and relieving oneself due to the inability to use the left hand to completely cleanse oneself from impurities?

Most scholars dislike using the right hand for istinja’ (cleaning oneself after relieving oneself), and some prohibit it, due to the established prohibition from the Prophet, peace and blessings of Allah be upon him. However, if there is a valid excuse preventing the use of the left hand for istinja’, such as an amputation, paralysis, or surgery, then there is no dislike in such a case due to necessity. If it is possible to remove some of the impurity with the left hand without hardship, that is preferable, based on the Almighty’s saying: "So fear Allah as much as you are able."
