Performing Prayers in a Standing Position with an Artificial Leg
Sometimes, handicap persons who use artificial legs and perform prayer in a standing position get tired and because of the possibility of injury they remove the artificial leg and perform their prayers in a sitting position. Is it obligatory for these people to always perform their prayers in a standing position with the help of artificial legs or is it permissible for them to perform their prayers in a sitting position in these cases?
If it is not too difficult for them, they need to perform their prayers in standing position, even though they do it by using a cane and the like. However, if it causes them much difficulty and discomfort, they can perform their prayers in a sitting position.
Having Fecal Bag during Prayer
A person, has had a major intestine surgery, and their rectum is blocked and their feces is collected in a bag; how should such a person perform their prayer?
There is no issue with this if the bag is carried with them. Furthermore, if the body is contaminated they should wash it if it is not too difficult for them, and if it is too difficult for them to wash their body, they can perform their prayer in whatever state they are in.
