She does not shake hands with a non-mahram man

It is natural that a Muslim woman who does not mix with men would not wish to shake hands with anyone who is not her mahram, in accordance with the teaching and example of the Prophet (PBUH). Bukhari reports that `A'ishah (May Allah be pleased with her) said:

"When the believing women made hijrah to the Prophet (PBUH), he would examine and test them, in accordance with the ayah: ( `O you who believe! When there come to you believing women refugees, examine [and test] them'. . .) (Qur'an 60:10)

Whoever accepted these conditions required of the believing women has thereby accepted their bay`ah. When the Messenger of Allah (PBUH) accepted their words, he told them (the women), `You may go now, for I have accepted your bay`ah.' By Allah (SWT), the Prophet's hand never touched the hand of a woman; he accepted their bay`ah by words only. By Allah (SWT), he never put any conditions on women other than those that Allah (SWT) commanded him, and when he had confirmed the bay`ah he would say `I have accepted you bay`ah by your words.'"91
