The sphere of prophethood's work in reforming people:

And every nation possesses customs

and special methodologies in its worship,

and the system of its family,

its society, its politics, and its civilization,

so if prophethood appears in it,

then it does not eradicate these customs

nor does it set new customs for it,

rather it only establishes the just scale,

and distinguishes between them,

so whatever of them was conforming to the origin,

matching the pleasure of Allah - the Most High - it kept it and preserved it,

and whatever of them was contrary to the pleasure of Allah - the Most High - it kept it and preserved it,

and whatever of them was contrary to the origin,

repugnant to the pleasure of Allah - the Most High - it adjusted it according to necessity and straightened it.

Likewise is the reminding of the bounties of Allah,

and the reminding of the days of Allah - upon this method -

with what is known among them,

prevalent among them,

so this is the reason for the difference in the laws of the prophets - upon them be the prayers of Allah and His peace -.

The difference of the laws of the prophets is like the difference in descriptions of the physician:

And this difference in the laws of the prophets

is like the difference in the prescriptions of the physician,

for indeed upon treating two persons of different temperaments,

he prescribes for one of them cooling medicines and foods,

and for the other warming medicines and foods,

and the purpose of the physician from treating them is one,

and it is the reforming of his temperament,

and the removal of the corruption incoming upon him,

nothing other than that,

and it is possible that the physician prescribes for every region different medicines and foods that suit its people,

just as
