I discussed the above matter with his holiness the Grand Ayatullah Makarim before translating the comments on the verse (NO.23). His holiness said a joke to clear this, which interested me much. His witicism was as follows:-
``When Potiphar bought Joseph the Dreamer as a slave boy, he took him home and introduced Joseph to his beautiful young wife, and said to her:-
``Treat the boy with honour, and respect his position, perhaps he may profit us.''
In answer to her impotent husband, when the young beautiful lady saw that attractive and well-built boy, said:- ``He needs not any recommendation for that.''
So is the case with the above reward that one may ask us to give him. The prophet needed not to recommend his followers to love their own kith and kin, because it was as natural as parental love.
