When she reaches her destination and becomes clean should she read qasr or not
In the name of Allah the most Gracious the most Merciful
The answer to your question is as follows:
If the lady reaches her destination and intends to stay there for 15 days or more, she has to perform full salah i.e. 4 rakats. However, if she is there only for few days i.e. less than 15 days, she will have to do Qasr and instead of performing 4 rakats of obligatory prayers she should perform only 2.
And Allah knows best
