Had it not been for the Grace of Allaah...

 يَا أَيُّهَا الَّذِينَ آمَنُوا لَا تَتَّبِعُوا خُطُوَاتِ الشَّيْطَانِ ۚ وَمَن يَتَّبِعْ خُطُوَاتِ الشَّيْطَانِ فَإِنَّهُ يَأْمُرُ بِالْفَحْشَاءِ وَالْمُنكَرِ ۚ وَلَوْلَا فَضْلُ اللَّهِ عَلَيْكُمْ وَرَحْمَتُهُ مَا زَكَىٰ مِنكُم مِّنْ أَحَدٍ أَبَدًا وَلَٰكِنَّ اللَّهَ يُزَكِّي مَن يَشَاءُ ۗ وَاللَّهُ سَمِيعٌ عَلِيمٌ

O you who believe! Follow not the footsteps of Shaitan (Satan). And whosoever follows the footsteps of Shaitan (Satan), then, verily he commands Al-Fahsha' [i.e. to commit indecency (illegal sexual intercourse, etc.)], and Al-Munkar [disbelief and polytheism (i.e. to do evil and wicked deeds; to speak or to do what is forbidden in Islam, etc.)]. And had it not been for the Grace of Allaah and His Mercy on you, not one of you would ever have been pure from sins. But Allaah purifies (guides to Islam) whom He wills, and Allaah is All-Hearer, All-Knower.

Surah an-Noor [24:21]
