The carotid artery is between the head and the neck which links vertebral column, spinal cord and all body joints. When a person wipes his neck during Wudu, the rays emitting from the hand enters the carotid artery and transmits to all sections of the neurological system via vertebral column, strengthening the neurological system.
Someone has stated, ‘I was doing Wudu at a place in France while a person looked at me, standing surprisingly. After I completed Wudu, he asked me who I was and where I belonged to? I answered that I am a Muslim from Pakistan. He then asked me how many mental asylums there are in Pakistan. I was surprised to have listened to this strange question; however, I replied that there might be two to four such asylums. He asked me what I was doing few minutes back. I replied that I was performing Wudu. He asked whether I do so daily. I replied that I do so five times daily.
