By this strategy of the Holy Prophet(sa) to have a ring prepared, by consultation of his companions, fundamental light is shed on how the Holy Prophet(sa) would employ all such ways in the work of preaching, as were necessary in attracting his addressee towards him, and in producing a positive effect on his heart. Obviously, as far as sheer preaching is concerned, having or not having a ring is an irrelevant matter. A true word is just as cogent without a seal, as it would be with one, but since the Holy Prophet(sa) was told that the rulers of this day and age do not give any significance to a letter without a seal, he did not wish to ignore any such aspect as would give rise to a condition of indifference in the heart of the addressee. For this reason, the Holy Prophet(sa) very particularly acted upon this minor detail, so that no flaw was left in his preaching that would render it ineffective. Indeed, this is the practical example of the Qur’ānic verse:
O Messenger! In the matter of preaching Islām, follow the course which is most effective in influencing the heart and mind of your addressee.”1
