Is it permissible for a woman to travel by plane with her mother and siblings to visit Egypt, given that she has a two-year-old daughter, under the current circumstances?

Using the right hand for istinja (definition)' (washing after defecation/urination) is disliked due to the hadith (definition) narrated by Salman al-Farisi: "The Messenger of Allah, peace and blessings be upon him, forbade us from performing istinja' with the right hand." However, there is no harm in using the right hand for istijmar (cleaning with stones) because it is merely removing impurities and not directly touching the private parts. Using the left hand for istinja' is preferable.
