Is ablution after tayammum sufficient for janabah when one is able to perform it, or must tayammum be repeated every time one breaks their wudu or wishes to pray?

If a person is required to perform ghusl (definition) (ritual bath) but cannot find water or fears harm from using it, they should perform tayammum (definition) (dry ablution) instead. This is based on the Almighty's saying: "And if you do not find water, then perform tayammum with clean earth." If a person in a state of janabah (definition) (major ritual impurity) performs tayammum and then incurs a minor ritual impurity, their tayammum for janabah is not invalidated. They must perform wudu (ablution) for their minor impurity if they are able to do so. This is based on the principle that tayammum temporarily lifts the impurity, and that the purity from janabah is not nullified by a minor ritual impurity.
