How can a man who belongs to the misguided Habashi sect be guided to the straight path and the correct Sunnah?

Warnings have previously been issued against the Habashis and their misguided beliefs, and scholars have written books on this matter. To advise someone affiliated with them, the advice should be given by a knowledgeable student of religious science, or by gifting them a book refuting the Habashis, without engaging in debate with those who are not qualified, especially in front of common people. The advice must be given with wisdom and good admonition, and similarly, advice to the wife should be conveyed in an appropriate manner.
