Narrated Abu Bakr ibn Abi Shaybah, narrated Husayn ibn Ali al-Ju'fi, from Za'idah, from Sulayman, from Abu Salih, from Abu Hurayrah, from the Prophet (peace be upon him) who said: "Madinah is a sacred precinct. Whoever commits an offense therein or gives shelter to an offender, upon him is the curse of Allah, the angels, and all of mankind. Neither his obligatory nor supererogatory deeds will be accepted from him on the Day of Resurrection."
