The Fahsha of Satan (Shaytaan) for he is your open enemy

أَلَمْ أَعْهَدْ إِلَيْكُمْ يبَنِى ءَادَمَ أَن لاَّ تَعْبُدُواْ الشَّيطَـنَ إِنَّهُ لَكُمْ عَدُوٌّ مُّبِينٌ - وَأَنِ اعْبُدُونِى هَـذَا صِرَطٌ مُّسْتَقِيمٌ - وَلَقَدْ أَضَلَّ مِنْكُمْ جِبِلاًّ كَثِيراً أَفَلَمْ تَكُونُواْ تَعْقِلُونَ

O Children of Adam! Did I (Allah) not ordain for you that you should not worship Satan? Surely, he is a plain enemy to you. And that you should worship me (Allah); That is the right way. Indeed he (Satan) has led a great number of you astray; Did you not then understand? [Sura Yasin 36: 60-62]

الشَّيْطَـنُ يَعِدُكُمُ الْفَقْرَ وَيَأْمُرُكُم بِالْفَحْشَآء وَاللَّهُ يَعِدُكُم مَّغْفِرَةً مّنْهُ وَفَضْلاً وَاللَّهُ وسِعٌ عَلِيمٌ

Satan threatens you with poverty and orders you to commit Fahsha (evil deeds, illegal sexual intercourse, sins etc.), whereas Allah promises you forgiveness from Himself and bounty. Allah is Self-Sufficient, All-Knowing. [Sura Al-Baqarah 2:268]
