What is the optimal methodology for da'wah in an environment where Sufism is prevalent and sound doctrine is scarce? Is it advisable to begin by reconciling hearts before addressing matters of halal and haram and Tawhid? Are there specific books or fatwas that can be utilized for this purpose?

We advise you to endear people to faith and draw them closer to Allah Almighty by mentioning His blessings, His beautiful names, and His sublime attributes. Encourage them in what is agreed upon among Muslims, such as their ethics and noble characteristics. Endear the Prophet, peace and blessings be upon him, to them by mentioning his qualities and virtues, then clarify that true love is through following him. Focus on issues of Tawhid (monotheism), using accessible books, and postpone discussions on controversial issues that might lead to harm.
