What is the response to those who say it is permissible to shake hands with women?

Question:
Your Eminence the Shaykh! This man brought a slip of paper. He says: Your Eminence the Shaykh! We ask Your Eminence to read this fatwa which states that it is permissible to shake hands with women, and to clarify the truth in this matter?

Answer:
Let me read it. It says: We request clarification of the Islamic ruling on a man shaking hands with a non-mahram woman without a barrier. It is not permissible to shake hands with women except with mahram relatives specifically. As for shaking hands with a non-mahram, it is not permissible. The Prophet (peace and blessings be upon him) said: He only pledged allegiance to them with words. So, do not shake hands with women, whether young or old, without a barrier or with a barrier. But speak to them and greet them without shaking hands, such as his brother’s wife, his uncle’s wife, his neighbors, his cousins. He speaks to them and greets them, but without shaking hands, and without uncovering. She does not uncover herself for him, but with the hijab, without shaking hands. Some people kiss the head, but kissing the head is also not permissible.
