Divine protection of the innocent

وَٱسْتَبَقَا ٱلْبَابَ وَقَدَّتْ قَمِيصَهُۥ مِن دُبُرٍ وَأَلْفَيَا سَيِّدَهَا لَدَا ٱلْبَابِ ۚ قَالَتْ مَا جَزَآءُ مَنْ أَرَادَ بِأَهْلِكَ سُوٓءًا إِلَّآ أَن يُسْجَنَ أَوْ عَذَابٌ أَلِيمٌ

And they both raced to the door, and she tore his shirt from the back, and they found her husband at the door. She said, "What is the recompense of one who intended evil for your wife but that he be imprisoned or a painful punishment?"

وَإِن كَانَ قَمِيصُهُۥ قُدَّ مِن دُبُرٍ فَكَذَبَتْ وَهُوَ مِنَ ٱلصَّـٰدِقِينَ

But if his shirt is torn from the back, then she has lied, and he is of the truthful."
