Muhammad b. al-Hasan b. Ahmad b. al-Walid (rh) narrated to us. He said: Muhammad b. al-Hasan al-Saffar narated to us from Ahmad b. Abi `Abdillah al-Barqi from his father from another person from al-Sadiq Ja`far b. Muhammad (as). He said
Do not anger others, or else you will be angered; and do not dig a hole for your brother, or else you will fall in it. Surely, you will reap what you sow.
