833 - Muhammad ibn Sa'id al-'Attar informed us, saying: Ali ibn Yazid al-Sudai related to us, saying: Abu Shaybah al-Jawhari related to us, from Anas, from the Prophet (peace and blessings of Allah be upon him) who said: 'Whoever insults my Companions, upon him is the curse of Allah, the angels, and all of mankind. Allah will not accept from him any mandatory or supererogatory deed on the Day of Resurrection.'
