8. He said: Abu Nasr Muhammad ibn al-Husayn al-Baseer reported to me from ‘Ali ibn Ahmad ibn Sa’yabah, who reported from Umar ibn Abd al-Jabbar, from his father, who reported from ‘Ali ibn Ja’far ibn Muhammad, from his brother Musa ibn Ja’far, from his father Ja’far ibn Muhammad, from his father, from his grandfather, peace be upon them, who said: The Prophet, peace be upon him and his progeny, one day said to his companions: "Be it known that an evil from the bygone people has crept into you, and that is envy and jealousy. It does not shave off the hair, it shaves off the faith. A man can save himself from that if one controls his hands, spares his speech and does not slander his Mu’min brother." And may Allah bless our master, Muhammad, the Prophet and his pure progeny.
