Answered by Shaykh Amjad Rasheed
Is it sunna to shake hands with for both men and women?
Answer:

Yes, it is sunna mu’akkadah (confirmed sunna) to shake hands when men meet with men and women meet with women. The hadiths about it are very well-known and are mentioned in the Adkhar of Imam al-Nawawi and other books where it mentions its rulings. So the questioner should refer to such works because they have many benefits.
