How To Clean Myself From Impurities
The principle of Quran is: لَا يُكَلِّفُ ٱللَّهُ نَفْسًا إِلَّا وُسْعَهَا [This is a fact that] God does not burden a person beyond his capacity . (Quran 2:286) Which means that one has to follow directives of religion that are within one’s capacity, as soon as something goes beyond one’s capacity, there will be no accountability. With your specific circumstance, being a converted muslim, you do not have to go through unusual difficulty in cleaning after relieving yourself. Whatever you can do in your normal capacity to clean yourself without letting it become too much difficult for you, you can stop at the instant. Secondly, cleaning the body after excretion and urination is required, no method has been prescribed in this regard, although water is recommended, but any other mean can also be used for such cleaning e.g. toilet roll etc.
