What is the ruling on touching women in crowded situations on buses or when giving charity to a woman, knowing that it may be unlawful?

Touching non-mahram women is Islamically forbidden, and a severe warning has been issued concerning it, as the Prophet, peace and blessings be upon him, said: "For one of you to be stabbed in the head with an iron needle is better for him than to touch a woman who is not lawful for him." However, touching her unintentionally, such as in a crowd, incurs no blame. When giving charity to a non-mahram woman, it must be placed in her hand without physical contact, or placed in a spot where she can take it herself.
