The slaughtered lament

What is the secret of that sacred place located in that Egyptian village, which its people venerate? They say it is for Sheikh Nuh who lived there long ago, his enemies slaughtered him but he did not die, rather God concealed him from everyone.. to return in the village streets at night to take revenge on the oppressors.. only the oppressors.. but, why does Aziza and her family not believe in him?
