Q 2: In most cases when I ride a bus it is congested.
Then, is it better to remain sitting when I find an aged person who wants to sit or to stand and try to make a room for him? It is worth mentioning that this may result in touching women on the way.
If the reality is as you mentioned that making a room will result in touching women, you should stay still in your place to escape the causes of temptation and evil.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
