﴿ ۞ يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ لَا تَتَّبِعُوا۟ خُطُوَٰتِ ٱلشَّيْطَٰنِ ۚ وَمَن يَتَّبِعْ خُطُوَٰتِ ٱلشَّيْطَٰنِ فَإِنَّهُۥ يَأْمُرُ بِٱلْفَحْشَآءِ وَٱلْمُنكَرِ ۚ وَلَوْلَا فَضْلُ ٱللَّهِ عَلَيْكُمْ وَرَحْمَتُهُۥ مَا زَكَىٰ مِنكُم مِّنْ أَحَدٍ أَبَدًۭا وَلَٰكِنَّ ٱللَّهَ يُزَكِّى مَن يَشَآءُ ۗ وَٱللَّهُ سَمِيعٌ عَلِيمٌۭ ﴾

“O You who have attained to faith! Follow not Satan’s footsteps: for he who follows Satan’s foot­steps [will find that], behold, he enjoins but deeds of abomination and all that runs counter to reason. And were it not for God’s favour upon you and His grace, not one of you would ever have remained pure. For [thus it is:] God who causes whomever He wills to grow in purity: for God is all-hearing, all-­knowing.”

To follow in the footsteps of Satan means acting upon his secret evil promptings. When for no reason at all the mind of an individual is suddenly flooded by feelings of suspicion, when a man begins harbouring negative thoughts about his opponents, it is the insidious work of Satan. Therefore, when such thoughts and feelings take shape, man should, instead of cultivating them, immediately root them out from his heart. To cultivate such feelings amounts to following Satan.To raise a hue and cry against others is inconsistent with humility. There are certain individuals who have very high opinions of themselves, while holding unduly bad opinions about others. Neither trait is in consonance with faith. If a man cultivates faith-oriented humbleness, he becomes so engrossed in introspection that he has absolutely no time to engage himself in unfair criticism of others or in calling others to account.
