Hazrat Uthman bin Abi Al-Aas narrates that I presented myself before the Messenger of Allah (peace and blessings be upon him) and said: O Messenger of Allah (peace and blessings be upon him)! Indeed, Satan has come between me and my prayer and my recitation! So the Prophet (peace and blessings be upon him) said: This is a devil who is called Khanzab. So whenever you feel his presence, spit three times to your left side and seek Allah's protection from his evil.
