An-Nur 24:18

إِذْ تَلَقَّوْنَهُ بِأَلْسِنَتِكُمْ وَتَقُولُونَ بِأَفْوَاهِكُم مَّا لَيْسَ لَكُم بِهِ عِلْمٌ وَتَحْسَبُونَهُ هَيِّنًا وَهُوَ عِندَ اللَّهِ عَظِيمٌ

When you received it with your tongues and said with your mouths that of which you had no knowledge and thought it was insignificant while it was, in the sight of Allah, tremendous.

وَلَوْلَا إِذْ سَمِعْتُمُوهُ قُلْتُم مَّا يَكُونُ لَنَا أَن نَّتَكَلَّمَ بِهَـٰذَا سُبْحَانَكَ هَـٰذَا بُهْتَانٌ عَظِيمٌ

And why, when you heard it, did you not say, "It is not for us to speak of this. Exalted are You, [O Allah]; this is a great slander"?

يَعِظُكُمُ اللَّهُ أَن تَعُودُوا لِمِثْلِهِ أَبَدًا إِن كُنتُم مُّؤْمِنِينَ

Allah warns you against returning to the likes of this [conduct], ever, if you should be believers.

إِنَّ الَّذِينَ يُحِبُّونَ أَن تَشِيعَ الْفَاحِشَةُ فِي الَّذِينَ آمَنُوا لَهُمْ عَذَابٌ أَلِيمٌ فِي الدُّنْيَا وَالْآخِرَةِ ۚ وَاللَّهُ يَعْلَمُ وَأَنتُمْ لَا تَعْلَمُونَ

Indeed, those who like that immorality should be spread [or publicized] among those who have believed will have a painful punishment in this world and the Hereafter. And Allah knows and you do not know.

وَلَوْلَا فَضْلُ اللَّهِ عَلَيْكُمْ وَرَحْمَتُهُ وَأَنَّ اللَّهَ رَءُوفٌ رَّحِيمٌ

And if it had not been for the favor of Allah upon you and His mercy... and because Allah is Kind and Merciful.

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 وَلَـٰكِنَّ اللَّهَ يُزَكِّي مَن يَشَاءُ ۗ وَاللَّهُ سَمِيعٌ عَلِيمٌ

O you who have believed, do not follow the footsteps of Satan. And whoever follows the footsteps of Satan - indeed, he enjoins immorality and wrongdoing. And if not for the favor of Allah upon you and His mercy, not one of you would have been pure, ever, but Allah purifies whom He wills, and Allah is Hearing and Knowing.
