Ruling on Al-Mirghaniyyah or Al-Khatmiyyah Tariqah (Sufi order)

Question:

I am a monotheist but my household follow Al-Mirghaniyyah Tariqah (Sufi order) which is known here in Sudan as Al-Khatmiyyah. Since I was guided to monotheism, I started calling my family to follow it but they refuse, as I am the youngest son. Is it permissible for me to leave them and start calling other people? If I do so, will I be among those mentioned in the Ayah (Qur’anic verse), “O you who believe! Why do you say that which you do not do?” [Al-Saff: 2] The people I intend to call may say to me: “Go call your household first then call others.”

Answer:

Continue calling your family members and you can call others as well. You are not among those mentioned in the Ayah where Allah says: “O you who believe! Why do you say that which you do not do?” [Al-Saff: 2] As long as you are following the right path and calling your family and others to follow it. Allah is the Grantor of success and guidance and not you.

May Allah grant us success. May peace and blessings be upon our Prophet, his family and Companions
