[Prescribed for you, when any of you is approached by death and leaves behind some good, is to make testament in favour of his parents and kinsmen honourably - an obligation on those that fear]
The making of a testament and honouring it is another law prescribed in order to remove the deficiency of the possessive faculty, that is to say, the faculty of [rational] speech, and its [that faculty's] falling short of the wisdom required to dispose of wealth and to have mastery over the other two faculties by means of the light of the Truth and the stipulations of the Law and also to prevent these [faculties] from any aggression in the way of changing the testament [in question], which is a kind of crime and a betrayal; [the law is also meant] to incite that [rational faculty] to verify and scrutinise the wisdom that constitutes its perfection by setting things right among those for whom the testament is made in accordance with wisdom when any harm is anticipated or known from the part of the testator, be it inadvertent or intentional. Fasting is another law that has been prescribed to eliminate the aggression of the bestial faculty and its power of control. The right to retaliation of the people of the truth is as has been mentioned and the testament for them [to honour] is to uphold the pre-eternal covenant by shunning all that is other than the Truth, as God, exalted be He, says, And Abraham enjoined this upon his sons and [so did] Jacob [Q. 2:132]. Their fast is to abstain from any speech, act, movement, or rest that is not [performed] in truth for the sake of the Truth.
