Narated By A number of Companions of the Prophet : Safwan reported from a number of Companions of the Apostle of Allah (pbuh) on the authority of their fathers who were relatives of each other. The Apostle of Allah (pbuh) said: Beware, if anyone wrongs a contracting man, or diminishes his right, or forces him to work beyond his capacity, or takes from him anything without his consent, I shall plead for him on the Day of Judgment.
