ما يُسَلِّطُ الشَّيطانَ That Which Brings One Under Satan's Authority

15ـ رسولُ اللهِ‏ِ (صَلَّيَ اللهُ عَلَيهِ وَ آلِهِ): بَينَما موسى (عَلَيهِ الّسَلامُ) جالِساً إذ أقبَلَ إبليسُ... قالَ موسى: فَأخبِرْني بِالذَّنبِ الذي إذا أذنَبَهُ ابنُ آدَمَ استَحوَذتَ علَيهِ . قالَ: إذا أعجَبَتهُ نَفسُهُ ، واستَكثَرَ عَمَلَهُ ، وصَغُرَ في عَينِهِ ذَنبُهُ.

15– The Prophet (SAWA) narrated, ‘Moses (AS) was once sitting down when Iblis [Satan] approached him … Moses asked him, 'So inform me about the sin which if the son of Adam were to commit would give you mastery over him.’ He replied, 'When he feels proud of himself [for a particular action], and continues to perform that action, deeming his sin insignificant.’[al-Kafi, v. 2, p. 314, no. 8]
 

16ـ الإمامُ عليٌّ (عَلَيهِ الّسَلامُ): مُجالَسَةُ أهلِ الهَوى مَنساةٌ للإيمانِ ومَحضَرَةٌ للشَّيطانِ.

16– Imam Ali (AS) said, 'Sitting in the company of people who are driven by their base desires is the key to obliviousness of one's faith and is the very seat of Satan's presence.’[Nahj al-Balagha, Sermon 86]
 

18ـ الإمامُ الصّادقُ (عَلَيهِ الّسَلامُ): ليسَ لاِءبليسَ جُندٌ أشَدَّ مِنَ النِّساءِ والغَضَبِ.

17– Imam al-Sadiq (AS) said, 'Satan's strongest forces are [mobilized through] women and anger.’[Tuhaf al-`Uqoul, no. 363]
