Al-Miqdad ibn al-Aswad reported that the Messenger of Allah, may Allah
bless him and grant him peace, asked his Companions about fornication and
they said, "It is unlawful. Allah and His Messenger have made it unlawful."
He said, "It is less serious for a man to fornicate with ten women than for
him to fornicate with his neighbour's wife." Then he asked them about stealing.
They replied, "It is unlawful. Allah and His Messenger have made it unlawful."
He said, "It is less serious for a man to steal from ten houses than it is
for him to steal from his neighbour's house."
