إِنَّمَا ذَلِكُمُ الشَّيْطَانُ يُخَوِّفُ أَوْلِيَاءهُ{That is only Satan who frightens [you] of his supporters.}: Who is afraid? They are the supporters of Satan, and Satan cannot enter a person except through a loophole in him. Allah (swt) says:

إِنَّ عِبَادِي لَيْسَ لَكَ عَلَيْهِمْ سُلْطَانٌ إِلاَّ مَنِ اتَّبَعَكَ مِنَ الْغَاوِينَ

{Indeed, My servants – no authority will you have over them, except those who follow you of the deviators.} (Al-Hijr: 42)

But Satan (may Allah curse him), promised:

قَالَ فَبِعِزَّتِكَ لَأُغْوِيَنَّهُمْ أَجْمَعِينَ % إِلَّا عِبَادَكَ مِنْهُمُ الْمُخْلَصِينَ

{[Iblees] said, “By you might, I will surely mislead them all % Except, among them, Your chosen servants.”} (Saad: 83)

If a person is sincere to Allah (swt), Satan will not be able to enter him through any loophole; Because the person is immune, but the devil can just frighten, so whoever is afraid, he is the supporter of Satan, and whoever is not afraid and has increased in faith and said: “Sufficient for us is Allah and He is the best Disposer of affairs”, then Allah (swt) is his protector.

فَلاَ تَخَافُوهُمْ وَخَافُونِ إِن كُنتُم مُّؤْمِنِينَ {So fear them not, but fear Me, if you are [indeed] believers.}: Allah (swt) confirms it for all generations and through all times. Man does not fear anything but Allah (swt); Because all matters are in His hand alone. Ibn Abbas (may Allah be pleased with him) said: “One day I was riding behind the Prophet (saws), he said to me:

“O young man, I shall teach you some words [of advice]: Be mindful of Allah and Allah will protect you. Be mindful of Allah and you will find Him in front of you. If you ask, then ask Allah [alone]; and if you seek help, then seek help from Allah [alone]. And know that if the nation were to gather together to benefit you with anything, they would not benefit you except with what Allah had already prescribed for you. And if they were to gather together to harm you with anything, they would not harm you except with what Allah had already prescribed against you. The pens have been lifted and the pages have dried.”[1]

This is the faith, and who has faith, fears none but Allah swt.
