Ibn Taymiyyah commented (‘Majmu’ al-Fatawa’; 1/77-78) on the verse: {“It is only Satan that suggests to you the fear of his allies. So, do not fear them, and fear Me if you are believers.”} [Al 'Imran; 175]:
“So, this verse proves that Satan makes his allies sources of fear, and he causes people to be afraid of them. And the verse shows that it is not permissible for the believer to fear the allies of Satan, and he should not fear people, as it was Said: {“So, do not fear the people, and fear Me…”} [al-Ma'idah; 44] So, we are commanded to fear Allah, and we are prohibited from fearing the allies of Satan. Allah Said: {“…So that men may have no argument against you except those of them that are wrong-doers. So, fear them not, and fear Me!”} [al-Baqarah; 150] So, He prohibited the fear of the wrong-doer, and He commanded us to fear Him.
He also Said: {“Those who convey the message of Allah and fear Him, and fear none except Allah…”} [al-Ahzab; 39] And He Said: {“…and fear Me, alone…”} [an-Nahl; 51]
