Yusuf - 12:27

وَإِنْ كَانَ قَمِيصُهُ قُدَّ مِن دُبُرٍ فَكَذَبَتْ وَهُوَ مِن الصَّادِقِينَ
[12:27]
And if his shirt is rent from behind, she tells a lie and he is one of the truthful.
"But if it be that his shirt is torn from the back, then is she the liar, and he is telling the truth!"
And if his shirt is torn from behind, then she hath lied and he is of the truthful.
