How do we call Sufis to the path of truth, and what are the proofs from the Qur'an and Sunnah that can be used for that?

To invite Sufis to the path of truth, the caller must possess sufficient knowledge of Islamic law and Sufi beliefs, and be characterized by good morals and compassion, inviting them kindly without harshness. It is advisable to avoid disparaging their symbols, focusing instead on mentioning the Prophets, Companions, and Imams known for their upright methodology. It is preferable to begin by mentioning the general principles of Islam and clear doctrines, avoiding direct criticism of their beliefs initially. There should be frequent mention of the Prophet (peace be upon him) and his biography, and discussions about softening hearts. One can benefit from the programs of contemporary callers and gifting them their books. Avoid directing them initially to books that disparage Sufi symbols, and increase supplication and seeking advice from scholars.
