In the Name of Allah, Most Gracious, Most Merciful.
All praise and thanks are due to Allah, and peace and blessings be upon His Messenger.
In this fatwa:
Answering your question, Dr. Muhammad Salama, PhD, Islamic Studies in English, Associate Professor at the Faculty of Islamic Sciences al-Madinah International University (Mediu), states:
A group of scholars hold the view that wiping the neck during wudu (ritual ablution) is permissible.
Therefore, the majority of scholars maintain that this practice is not recommendable. Even some scholars label this practice as bidah (heretical innovation); particularly if practiced regularly.
Almighty Allah knows best.
