Rather than attacking individuals and beliefs...
Rather than attacking individuals and beliefs, Shī‘ites should speak exclusively about the Prophet, citing the Qur’ānic verses and aḥādīth in favor of the ahl al-bayt . Presented properly, by means of an intelligent, tolerant, and respectful approach, the Shī‘ite message is sure to have greater resonance among Sunnī Muslims.
In order to guide an interested Sunnī into Shī‘ite Islām, all one has to do is cite the Qur’ān, repeat the words of the Prophet, and demonstrate the wisdom of the Imāms, and that will be sufficient. One must address issues of faith, and the importance of the imāmah and wilāyah , before tackling controversial issues from the early days of Islamic history.
Once a person is open to the divine authority, everything else will fall into place, and then, and only then, are individuals interested in Shī‘ism ready to deal with Tijanī’s informative works*.* In our experience, works like Then I was Guided , Ask those who Know , To be with the Truthful , and The Shī‘ah are (the Real) Ahl al-Sunnah have an important place, but not necessarily in the first line of da‘wah .
Many Shī‘ite Muslims seem to forget that taqiyyah is a form of tact and every educational endeavor must proceed by stages. As Imām Ja‘far al-Ṣādiq has said, “This affair ( amr ) [the Imāmate and the esoteric meaning of religion] is occult ( mastūr ) and veiled ( muqanna‘ ) by a covenant ( mīthāq ), and whoever unveils it will be disgraced by Allāh” (Kulaynī). Certain things are better left unsaid when dealing with people who are potential enemies of ahl al-bayt .
As Imām Ja‘far al-Ṣādiq warned: Keep our affair secret, and do not divulge it publicly, for whoever keeps it secret and does not reveal it, Allāh will exalt him in this world, and put light between his eyes in the next, leading him to Paradise...Whoever divulges our affair publicly, and does not keep it a secret, Allāh will disgrace him in this world and will take away light from between his eyes in the next, and will decrease for him darkness that will lead him to the Fire...Taqiyyah is of my religion, and of the religion of my father, and who does not observe taqiyyah has no religion...It is necessary to worship in secret and it is necessary to worship openly...the one who reveals our affairs is the one who denies them.
