Yusuf 12:27
وَإِن كَانَ قَمِيصُهُۥ قُدَّ مِن دُبُرٍ فَكَذَبَتْ وَهُوَ مِنَ ٱلصَّـٰدِقِينَ
Wa-in kana qameesuhu qudda minduburin fakathabat wahuwa mina assadiqeen
But if his shirt is torn from the back, then she has lied, and he is of the truthful."
and if his shirt was ripped from behind, then she is telling a lie and he is truthful.
